Comparing Evaporative Air Coolers and Air Conditioning Cooling Units

Evaporative Coolers Fundamentals, Pros and Cons

If you are looking for some way of cooling a area most new users consider air conditioning and evaporative air coolers to be one of the same. There is a fundamental difference in the way an air cooler works when compared to refrigerant based air conditioning unit.  Evaporative air coolers use water as its medium of cooling, the water is pumped over a thin sheet of specially treated paper, perforated with air gaps to allows air to pass through which allow evaporation of the water to take place when a forced air fan drives air across it..

The evaporating water cools the passing air and a cooling effect occurs. Air coolers have a limited cooling effect output as the cooling effect it produces isn't powerful enough due to its basic design capabilities when compared with air conditioning. Because a evaporative air cooler doesn't come with a Kw/Btu output rating this makes them impossible to match against a heat load such as a server room or computer ladened room.

Because of the water associated with the cooling effect of evaporation and the need to constantly fill with water, evaporative air coolers are not suitable to be used in areas where a high density of electronic equipment is being used. Evaporative air coolers add moister to the air which can cause in a sealed area particularly a build up of humidity in the room, in server rooms static can build up in low and high humilities and if the server cases are not earthed cause equipment damage. Most evaporative coolers stipulate that the room being treated requires some form of ventilation to prevent high humidity conditions.

Air Conditioning Can Directly Match The Heat Load

As conditioning uses refrigerant as its cooling medium the cooling effect it produces is vastly more powerful. A heat load in a area that needs cooling can be directly matched by the output of the air conditioning unit, this makes refrigeration driven air conditioning a more professional way of cooling. An air conditioning unit has the opposite effect to a evaporative air cooler as it  will remove moister from the air, humidity in the air being treated is removed by the cold evaporator coil and usually is collected in a bucket or pumped away.

Summery Evaporative Air Coolers or Air Conditioning?

Air conditioning systems match your heat load so are ideal for professional / commercial areas that require a "set temperature" such as server rooms.

Evaporative air coolers are ideal for residential or light commercial use such as a office.

Ducted air conditioning systems are amongst the most expensive types of air conditioning to buy

Whilst ducted air conditioning systems are amongst the most expensive types of air conditioning to buy and install, they will result in an inconspicuous air conditioning system with only diffusers in the ceiling being visible.

Ducted air conditioning systems are most effective in large commercial air conditioning systems and require specialist knowledge throughout their design and installation. Our expert ducting installation team will mount the ductwork above the ceiling to carry the air to the diffusers resulting in excellent coverage and a comfortable workplace environment. The diffuser grilles allow uniform temperature distribution in large or heavily partitioned areas. These systems are operational via keypad remote controls or wall mounted control panels.

All our air conditioning systems have a heat pump option in addition to their standard air conditioning feature. New technologies mean that these units are extremely quiet when running and have improved energy savings.

These units come with one outdoor condensing unit, known as a single split system and thanks to the flexibility of air conditioning systems, you can choose to run a number of units off of a single outdoor unit, which is known as a multi split. An larger version of this is a VRV/VRF air conditioning system which is commonly used in industrial facilities.

Portable Air Conditioner Titan-Cool TC25 (7.3 kW / 25000 Btu) Industrial Air Conditioning unit

The Titan-cool high output professional portable air conditioning unit comes in a robust metal construction and has tough casters for easier manoeuvrability. The unit is ideal for computer rooms, industrial kitchens, hospitals, disaster relief, marine vessels, workshops, spot cooling, emergency cooling, sports rooms, factories, temporary offices, military tents and hangers, laboratories, special events and marquees. The Titan-cool provides spot cooling for large areas where cooling of the entire area is not feasible.

The Titan-cool can also be used in small areas with the room being thematically controlled by the Titan-cool's thermostat. This portable air conditioning unit operates on a standard 13 Amp plug and is simple to set up as it is already assembled. The chilled air is directed with two flexible hoses on the front of the unit. This makes the Titan-cool mobile air conditioning ideal for spot cooling. The hot air extracted from the room is blown out the top of the unit and expelled up. It can be connected to 300mm ducting (9 meter’s sold separately) via the cowl (sold separately) and ducted away up to nine meters with the air conditioners high powered fan.

Air Conditioning energy efficiency has never been more important

Energy efficiency has never been more important. Every business has a need for it, every government has an agenda for it, and every vendor wants to tell you how they build it into their products. As manufacturers of some of the most efficient air-conditioning units on the market, Fujitsu knows more than most about energy efficiency. But it occurred to us that it is not just about the products. Every installer, specifier, contractor and architect is now expected to help tenants and users to get the most efficient use out of their air-conditioning systems. And there are a number of ways in which efficiency can be improved. So we have put together a short summary of the key factors that can affect the efficiency of your air conditioning. If this is the first time you have really considered this issue, we hope this will be a really useful guide and perhaps something of an eye opener to how energy efficiency works in the air-conditioning world. On the other hand, if you are an experienced HVAC practitioner, you will nevertheless appreciate a checklist to make sure you are covering every option and achieving the best levels of efficiency for your customers.
Energy efficiency can be impaired or improved (depending on your viewpoint) by a number of factors, including the following:


1. Planning ahead

It is always worth ‘planning ahead’ when considering the air conditioning of a space. Is it going to be for open plan usage or will it be zoned at a later date?
Where will the equipment be sited?
What is the future usage going to be?
Consideration of all these points will assist in selecting the right air-conditioning equipment for the application intended. Smaller ducted units will allow for future zoning of the space, whereas cassette type indoor units will restrict this. Spare a thought for the location of the indoor and outdoor units since excessive pipe runs should be avoided as a severe drop off in performance will be experienced. If considering the use of heat recovery VRF systems, try and create a balance of indoor
units that require heating with that of indoor units requiring cooling, in addition to giving consideration to building diversity. Always provide suitable service access for engineers to carry out effective system maintenance in accordance with the manufacturer’s recommendations.


2. Selection/sizing

Correct sizing and selection of air-conditioning equipment is key to achieving optimum energy efficiency. Over-sizing in itself doesn’t render the system operationally inefficient. However, increased power consumption over the lifetime of the system can prove otherwise. Alternatively, under-sizing the system can result in excessive operation during normal system lifetime and can cause premature failure. Of course, where possible, select A/A rated equipment with the latest in DC inverter technology. Ensure consideration is given to using the correct UK design criteria when choosing equipment, as nominal capacities normally quoted within manufacturers’ literature can result in the incorrect sizing of the equipment. It is also important to adhere to the manufacturers’ recommended pipe sizes and maximum pipe lengths as system capacity will reduce significantly if these are exceeded


3. Control/set point

The most energy-efficient air conditioning systems installed in any application can be rendered energy inefficient if not controlled in the correct manner. Most of today’s control options can greatly increase the efficiency of an air-conditioning system. Control of operation times and set-point temperatures are the most basic and fundamental of control functions that will enhance system efficiency. However, depending upon size and type of air conditioning system installed, more sophisticated
control systems should be considered so that additional functions such as ‘night set back’, centralised set-point control and occupation detection facilities can be utilised to improve operation. It is always worth asking users how they expect to use the space that is to be air conditioned. Also consider options available on air conditioning systems, such as Energy Saving and Economy modes. Always be aware of the competition by users to either have the maximum heating temperature set point compared to the lowest cooling set point. Centralised control should be considered for this instance as constant adjustment of the set point will only result in erratic operation of the system and a reduced level of efficiency, not to mention the most
uncomfortable conditioned space. Finally, avoid the possibility of independent systems ‘fighting’ against each other whilst in different operating modes, ie one system heating whilst another is cooling in the same space.

4. Refrigerant charge

Paying attention to refrigerant charge is important for any air-conditioning system. Undercharging will result in the starvation of refrigerant within the system, in turn reducing the ability of the refrigerant to absorb the required amount of energy to satisfy the heating or cooling demand of the conditioned space. Operation times will subsequently increase and defrost cycles will become more frequent creating higher risk of system failure and reduced capacity and space temperature control. If a system is undercharged, always check for leaks within the pipe work and equipment and repair or replace as necessary before re-charging. Also be aware that some refrigeration systems may also be subject to routine leakage testing requirements
under the F-gas regulation (EC Regulation No. 842/2006 on Certain Fluorinated Greenhouse Gases).Frequently, these issues stem from poorly planned installation in the first place that make inspection and maintenance difficult or even impossible. If the filter or coils cannot be inspected or cleaned, the system’s efficiency will be dramatically reduced as the airflow across the coils becomes restricted. Over time this will result in costly repairs to the condenser as the compressor will inevitably fail.

5. Insulation

Poorly insulated and/or damaged insulation on pipe work breaks the vapour seal flowing condensation to form on the pipe. This condensation can soak into the insulation destroying the thermal insulation properties. The resulting exposed pipes will decrease the system’s efficiency. Many split system expansion devices are located in the outdoor unit and poorly insulated pipe work can affect the efficiency of the air conditioning system. Exposed pipes will act like a heat exchanger and absorb or reject energy before the refrigerant reaches the indoor or outdoor unit
reducing the performance of the air conditioning system. Always ensure pipe work insulation is of the correct quality and standard as recommended by the manufacture and/or in line with good refrigeration installation practice.

6. Servicing and access

Too often, system maintenance is neglected – and even the most efficient air-conditioning systems will not fulfil their operating potential if not serviced
regularly. Regular maintenance checks will ensure your air-conditioning system operates as efficiently as possible. Energy consumption can increase by as
much as 60% as a result of replacing poorly maintained or dirty components. Simple routine maintenance such as checking and cleaning fans, filters, coils/heat exchangers and any associated ductwork will maintain system efficiency.
Frequently, poor planning with regards to system location makes it impossible for service engineers to gain safe and suitable access to units on routine maintenance visits. Reference should always be made to the manufacturer’s recommendations to
location and service space requirements as detailed within installation and maintenance manuals.

7. Air distribution

Good air distribution is key to an effective and efficient air-conditioning system. Where applicable, particular attention must be paid to effective and correct ductwork design so as not to impair airflow over the system. Consider the distribution of air into the conditioned space. Avoid ‘dead zones’ and draughts as they may lead to the occupants using the controls erratically. Always consider the usage of the space
and the furnishing within the space to avoid any possible ‘short circuiting’ of airflow.

8. Usage & the people factor

Understanding how and when to use your airconditioner is also a pre-requisite for energy efficiency. Basic functions such as fan speed and louvre angle can be adjusted to improve efficiency. Use external shading to reduce the amount of light/
heat entering a space, and louvres can be retrofitted to buildings to provide shade during summer whilst allowing lower winter sun to penetrate the area. Blinds can also be angled to reduce solar heat gains whilst reflecting light onto walls and ceilings to reduce demand for electric lighting. While these are all things you can do to boost efficiency, all this work can be undone by the ‘human factor’ – ie if occupants leave doors and windows open.

The answer is not usually to issue a set of rules, but to encourage staff involvement by demonstrating how they can be more in control of their own environment. Explain how thermostats operate and give guidance on recommended operating temperatures and on how to set heating or cooling units correctly. Display instructions on individual
units and ensure that remote controls are accessible. It has also been observed that where other energysaving measures are in place [eg PIR-activated lighting], users are more aware of their responsibilities and react by being less wasteful. This is more a people issue than a technical one, but vital to the overall performance and efficiency of a system.

This might sound like an evident definition but unless you recognize what you happen to be purchasing it is difficult to acquire the best air conditioning unit.

Many people seem to be beneath the impression that Air Conditioning is really a new invention but that’s just not the situation. In reality, air conditioning has become all around for 1000′s of many years but not within the sort that we know now. The Romans for instance employed air conditioning in their homes.
The Romans weren’t the only ones though. An additional illustration of the culture that utilised air conditioning is the Persians from the middle ages although there have already been lots of other individuals.

Even though air conditioning has become close to to get a although that does not suggest it’s effortless to get though, there are many things you’ll want to consider as well as the more you understand about air conditioning the less difficult it turns into.

Air conditioning is probably the greatest techniques to generate sure your place or house is comfy to be in.

Metal thieves getting jail for conspiring to release ozone-depleting substances.

IN WHAT is thought to be one of the first such cases of its kind, three thieves in Georgia, USA, convicted of stealing copper coils for scrap from air conditioning units, have pleaded guilty to additional charges of conspiring to release ozone-depleting substances.

The three men, Daniel Arnot, Corey Beard and Justin Joyner, were indicted in June last year on one conspiracy count and 12 counts of releasing R22 into the environment. As reported in ACR News (August 2010), this involved the dismantling of approximately 35 air conditioning units from 14 locations, including a church.

Arnot and Beard could now face millions of dollars in fines and up to 65 years in federal prison. Joyner, who only pleaded guilty to one count each of conspiracy and releasing ozone-depleting chemicals, faces a maximum jail sentence of 10 years. Sentencing dates have not yet been set. Arnot's wife is awaiting trial on similar charges.

As the price of raw materials rises around the world, thieves are cashing in by stealing metal for scrap. The popularity of air conditioning in the US makes the copper coils in the condensing units particularly attractive to thieves. With copper selling for around $3 a pound in the US, thieves can expect $1.50 a pound from scrap metal merchants.
