High Temperature Cold Climate Air Source Heat Pump Multiple Anti
Freeze Design
Cold Climate Air Source Heat Pump Feature
1. High quality famous brand components such as :Copeland
compressor, plate heat exchanger for main circuit and assistant
circuit ,Emerson expansion valve, Eaton contractor etc.
2. Optimized defrosting system.
3. With extra electric heater for fast drainage design for
condensing water from defrosting.
4. Every component is easily accessible for maintenance.
5. Low noise by low speed fans, complete isolation of compressor
noise and noise absorption material .
6. Considerate design to keep compressor warm including the
crankcase heater and closed space to avoid heat loss.

Cold Climate Air Source Heat Pump Applications
House, apartment, villa air heating or cooling.
In summer, it provide 7C cool water and in winter, it provide 50C
hot water
Water could be used in bath too.
ASHP VS Air Conditioner unit
The air source heat pump air conditioner belongs to the central air
conditioner of the water system. It uses water circulation
refrigeration, and the outlet air temperature is high and soft. The
temperature difference with the outdoor is not too large, and it is
not punctured when it is blown on the body. At the same time, it
can maintain the best indoor humidity environment and avoid indoor
drying. The air conditioner is a fluorine system. The main purpose
of the air conditioner at the beginning of the design is cooling.
Therefore, the accessories of the airframe are designed for
cooling. The air conditioner has a relatively high energy
efficiency conversion during cooling, and the air temperature is
relatively low. It will be relatively large, the interior will be
relatively dry, and it will be chilly when it is blown to the body,
and the cooling will be faster.
