What is the difference between air source heat pump engineering and heating and cooling engineering?

Date of release:2018-07-20 Author: Click:

First, the difference of work principle

Air source heat pump engineering: power driven compressor work, compression of low temperature refrigerant into high temperature refrigerant, high temperature refrigerant through hot water heat exchanger and water heat exchange, heat exchanger after heat transfer through the expansion valve to absorb the heat in the air after the evaporator, the heat absorption of the refrigerant is inhaled by the compressor, and continuously heat from the air, Heat the hot water heat exchanger on the side of the heat exchanger and heat the cold water. The heat absorbed by water is the sum of the heat generated by the compressor and the heat absorbed by the refrigerant.

Air conditioning engineering: power driven compressor work, compression of low temperature refrigerants into high temperature refrigerants, high temperature refrigerants through evaporator heat dissipation, air conditioning main engine fan put heat out of the outdoor, heat cooling medium after the expansion valve after the expansion valve depressurization through the air conditioning indoor evaporator absorption air heat, reduce indoor temperature, heat after the cold The medium was inhaled by the compressor. In this way, heat is continuously discharged from indoor to outdoor air, heat is absorbed from indoor to achieve the purpose of reducing indoor temperature.
Two. Difference in heating mode

Air source heat pump engineering: air energy heat pump itself is only a hot water supply equipment. It heating, and then combined with other heating ends to achieve heating, such as the radiator, fan coil, air heating machine, ground heating pipe can be used as its heating end, can choose different heating methods according to different houses.
Air conditioning engineering: Whether vertical air conditioning or wall hanging air conditioning, can only use the active way to achieve heating.
Three, the difference of parts and components

Air source heat pump engineering: special compressor for heat pump, antifreeze high efficiency tank condenser, outdoor fin heat exchanger with hydrophilic film, high pressure protection and control system.

Air conditioning engineering: air conditioning compressor, fin condenser or plate condenser, outdoor fin heat exchanger without hydrophilic film, no system high pressure protection control.

In these parts, the difference of compressor is the biggest difference between air source heat pump engineering and air conditioning engineering, because different compressor determines the use effect and different use area of the product. Air conditioning compressor selection air conditioning compressor, take R22 as an example, the maximum operating pressure is not more than 2MPa, the compressor ratio is less than 7, the maximum exhaust temperature is not more than 90 degrees, but the air source heat pump must use a heat pump compressor, the same as R22, the maximum operating pressure reached 3MPa, the compressor ratio reached 12, even higher to 20, the highest exhaust temperature. Up to 110 degrees centigrade. The difference of these parameters requires the improvement of the processing precision of the heat pump compressor, the strength of the bearing, the temperature resistance of the motor and so on.
