Energy Saving Central Air Source Heat Pump For Space Heating In
Winter
Central Air Source Heat Pump Brief introduction
1. Air source heat pump(ASHP)can achieve summer cooling and winter
heating through the “handling” of thermal energy. Heat pump heating
and cooling is the extension and development of air conditioning
technology, and compared with ordinary air conditioners, it adapts
to a wider range of ambient temperatures, and the effect of heating
and cooling is better.
2. In the central station,several units could be connected in
parallel and become central station with automatic control
center,providing air conditioning for several buildings.
3. Indoor , it could be connected with users' temperature control
facilities, allowing users to implement stratification, household,
compartment control, so that heat loss is minimized, and ultimately
save energy..
Central Air Source Heat Pump Features
1. Energy-saving: air source heat pump uses the principle of air energy, only a
small amount of electrical energy can be driven. By the low-grade
heat energy in the air, the heat exchange is performed through the
compressor to provide heating, air conditioning or hot water for
the end. A piece of electricity can produce three parts of heat,
which is very environmentally friendly and very energy efficient.
2, Comfortable : the use of air source heat pump heating and cooling, the overall
effect is better than the traditional radiator and air
conditioning. The most important thing is that the air source heat
pump belongs to the water system. It has high stability and can
maintain a constant indoor temperature. In addition, the heating
and cooling methods are closer to the human body's temperature,
which makes the refrigeration and heating more comfortable and will
not be given to the user. It feels hot and cold.
3, Total coverage: air source heat pump is an ideal choice for commercial housing,
villa buildings, commercial places, users install air source heat
pump, can cover all corners without dead angle, but also can
provide cold air to the kitchen, provide heating for the toilet, to
achieve comprehensive Energy consumption, energy saving and
environmental protection.

QC
Every process must be strictly operated and inspected by our
quality persons.
Some main points as below:
1. Check all parts before assembling.
2. Charge nitrogen to test leakage and pressure maintaining after
welding system.
3. Vacuumize, the vacuum pressure ≤30Pa
4. Leakage detection by halogen after charge refrigerant.
5. Safety testing: High-voltage insulation test and ground
resistance.
6. 100% Operation testing, record refrigerant pressure, temp. etc.
7. Inspect inside unit’s cleanliness and appearance.
8.Lables and package.
