WATERSTAGE air to water heat pump with enhanced heating performance by Fujitsu Air Conditioning
Purchace soon at www.orionairsales.com
Fujitsu air conditioning entered the market of heat pump type hot water heating system in Europe in March, 2009. In order to further strengthen the business of the heat pump type hot water heating system, we developed the new model of “WATERSTAGE®” with enhanced heating performance at the outdoor temperature -25°C and expanded the product lineup. The low outdoor temperature type will be released early in October.
The hot water heating system is an appliance to heat the room by passing the hot water heated by heat source through the pipe installed in the wall and floor. In Europe, the system to make hot water by burning gas or kerosene is commonly adopted but recently, energy-efficient heat pump type which does not emit CO2 is attracting attention as state-of-the-art technology to restrain the global warming. However, the conventional heat pump type hot water heating system had disadvantage that it can not retain the high hot water temperature and the heating capacity drops under the low outdoor temperature.
The low outdoor temperature compatible type developed this time made it possible to provide hot water of 60°C at low outdoor temperature of -20°C and hot water of 50°C at -25°C by “Linear control injection refrigeration cycle” (*1).
Furthermore, we have achieved the industry's top class(*2) COP(*3) 4.40 by enhancing the energy-saving performance adopting the “high response control” which optimizes the refrigeration cycle corresponding to the operating characteristics of the heat pump type hot water heating system. Thereby, the efficient hot water heating at the low outdoor temperature has been realized.
By adding the new product to the lineup, our company will aim to expand the air conditioning business in various countries in Europe together with air conditioners.
The conventional models are based on the specifications that the upper limit of highest hot water temperature is 50°C and have been sold mainly for newly built houses with high heat insulation efficiency as heat source appliance for low temperature panel heater and floor heating.
However, in order to cope with wide range of needs such as for already built houses with low heat insulation efficiency and cold district, the products which exert high performance under the condition of low outdoor temperature have been demanded.
Key Product features:
1. Realizing high hot water temperature at low outdoor temperature by adopting “linear control injection refrigeration cycle”
In the conventional refrigeration cycle which is commonly adopted, when hot water temperature was made higher, the compressor tended to be overheated and cause machine failure. Therefore, the overheating was suppressed by restraining the capacity of compressor, which caused the problem that the hot water temperature dropped due to the lack of capacity when outdoor temperature dropped.
The “linear control injection refrigeration cycle” realized the high hot water temperature by suppressing the overheating of compressor by cooling the compressor directly with refrigerant (liquid injection cooling) and enhancing the capacity at the low outdoor temperature.
This refrigeration cycle made it possible to provide hot water of 60°C at the outdoor temperature -20°C and hot water of 50°C at -25°C. Compressor for “linear control injection refrigeration cycle”
2. Enhancing energy-saving performance by “high response control” adopting twin sensor. By two sensors (twin sensor), it has become possible to control the refrigeration cycle condition in more detail than conventional models and make waste-free operation corresponding to the heating load.
Thereby, we have achieved the industry's top class(*2) COP(*3) 4.40 and enhanced the energy-saving performance in the actual use.

Dura 7 + Swimming Pool Air Heat Pump Heater (7 kw / 24000 Btu) Low Operating Temperature
www.orionairsales.co.uk
Dura 7 + Swimming Pool Air Heat Pump Heater (7 kw / 24000 Btu)
DURATECH® heat pumps utilize the sun’s free heat by collecting and absorbing energy from the outside air. This energy is then transferred to the pool water. Your existing pool pump circulates the water through the heater and warms the pool. The unit contains a fan that draws in outside air and directs it over the surface of the EVAPORATOR (energy collector). The liquid refrigerant within the EVAPORATOR coil absorbs the heat from the outside air and the refrigerant becomes a gas. The warm gas passes through the compressor where it is compressed to form a very hot gas, which then passes through the CONDENSOR (water heat exchanger). It is here that the heat exchange occurs as the hot gas gives up the heat to the cooler swimming pool water circulating through the coil. The pool water becomes warmer and the hot gas is cooling down as it flows through the CONDENSOR coil, returns to its liquid form and, after passing through the expansion valve, the whole process begins again. The use of a highly efficient, low sound rotary or scroll compressor, a low noise fan and an oversized heat exchanger, makes the unit to be extremely quiet in operation. Example: the DURA 8 at 10m distance gives only 32 db(A). The Dura range comes in two formats the standard and Dura+ range, the key differences being the Dura+ range will work down to a lower outside temperature -10*c and have a higher COP range over their operating temperature.
Key Product Feature's:
# Model: Dura 7+ (Output 7KW)
# Works down to outside air temperature -10*c
# Maximum pool volume 30 m3
# COP @ air temperature 25*c = 5.8
# Volts 220-240V single phase
# Maximum input current 6.5 amps
# Noise level 50db
# Refrigerant R410A
# Nominal water flow m3/h = 3
# Water connections 50mm
# Dimensions: L905, W420, H650
# Weight 55Kg
The unit is intelligently designed and remarkably compact for easy installation. The heat pump has to be installed on a by-pass after the filtration pump.

The integrated microprocessor monitors all the sensors and controls the device without any intervention of the user. Electronic display and control with easy operation is standard. The integrated flow switch will sense the water flow and automatically start the heater when the pool pump starts and stops when the pump shuts off.
