Winter Anti-freezing Running (only the air-cooled heat pump unit) Interlock contacts are preserved in the electric box. Under the circumstance that the unit is powered, the water pump or compressor can be started or stopped via sensing the environment temperature and water temperature so as to realize the auto anti-freezing protection function of the unit and overcome the shortcomings of low water temperature on duty due to the too large drop of water temperature after winter weekends or holidays.

100 per cent Unit Passed Working Testing Platform

All of the series of the water-cooled screw chiller water units have passed all of the assembly and factory tests before shipment and filled with cooling agent as well as freezing oil in the works. What the users need is only to connect with the water circulation as well as the electric circuitry and put the unit into use, which has made the unit locale installation and debugging time reduced to the utmost.

Brief Introduction to Water Source Heat Pump Unit

With water as carrier, the water source heat pump unit can utilize surface water (tap water, lake water and river water), ground water as well as geothermal tail water even low-grade thermal energies such as industrial wastewater, sewage or soil. In winter the water pump system can provide the room with heat supplies at the cost of part electric energy while in summer extract the indoor heat into water to realize the aim of cooling. The operation of the unit is rather simple, safe and reliable, with functions of environment protection and energy saving. The flowing direction of the refrigerants in the cooling machine is not necessary to be changed while the COP is rather high, which makes the unit a rather energy saving air conditioning cooling product.

Superiorities of Water Source Heat Pump Unit

Environment Protection The utilization of surface water as cooling and heating source eliminates the pollution due to coal, gas or oil, saves the space of boiler room and cooling tower and meanwhile, avoids the noise and mildew pollution of the cooling tower, making it rather in accordance with the requirements of environment protection and making the environment more and more beautiful.

High Efficiency, Water Saving & Energy Saving The temperature of groundwater in winter is around 1222ºC, which is higher than the environment temperature thus its evaporation temperature is relatively improved and so is the COP while its temperature in summer is around 1835ºC, which is lower than the environment temperature thus its condensation temperature is relatively reduced, the cooling heat exchange effect is excellent and the efficiency of the unit is improved.

Multifunction & Broad Application The water source heat pump unit can provide heating, cooling, air conditioning, craftwork and providing hot water for life use. The function of one unit two uses has been realized truly, improving the utilization ratio of the unit.

Lower Investment Since there is no need for centralized unit room, boiler room or air conditioner room, the area of equipment room is reduced. And there is also no need for cooling tower or other water pipeline system and water pipelines need no heat protection, thus the equipment construction charges are saved. According to the estimate of EPA, the water source heat pump designed and installed reasonably and properly can save 30-40% running charges of the heating or cooling air conditioners averagely.

Stable and Reliable Running The water temperature is relatively stable in the whole year, whose fluctuation is far smaller than that of air so it is rather good heating and cooling source, which can make the unit run more and more reliable and stable and ensure the high efficiency and economy of the system. Its running working condition is rather stable, design is simple, components are few, maintenance charges are low; and it is without any sanitary or safety hidden troubles such as coal or oil tank.
