Description
Technical field
The utility model is related to technical field of refrigeration equipment, more specifically, more particularly to air source heat pump wind-power electricity generation
Defrosting system and net for air-source heat pump units.
Background technology
Cooling and Heat Source of the net for air-source heat pump units as air-conditioning system, since its is easy for installation, runs the features such as easy to operate,
In recent years considerable progress has been obtained.But the area that outside air temperature is relatively low in winter, humidity is larger, when finned tube surface temperature
During less than air dew point temperature, the vapor in air will condense, and when this temperature is less than 0 DEG C, condensation is just with loose ice
The form of crystal is deposited in fin pipe surface and forms frost layer.With the progressive additive of frost layer, increase air and flow through fin
Resistance during pipe, reduces air mass flow, and insufficient, evaporating temperature reduction, evaporation are evaporated so as to cause fin tube refrigerant
The problems such as device outlet superheat degree is reduced, heating capacity is decayed, refrigerant flow reduces, will cause compressor thing when serious
Therefore.
It is commutated for this purpose, existing solution method is net for air-source heat pump units by four-way valve, using reverse cycle defrosting.Air
The classical pathway of source heat pump unit winter frost removing method, i.e. compressor shutdown, four-way valve are transformed into refrigeration mode by heating mode,
Compressor is opened, and heat pump unit is run by the refrigeration mode of original heating mode conversion till now, and outdoor heat exchanger is by steaming
Hair device becomes condenser, and the refrigerant vapour of the high temperature and pressure of compressor discharge enters outdoor heat exchanger, makes its surface temperature
Rise, frost layer is gradually melted and is removed, and so far defrosting mode terminates, and heat pump unit is once again into heat supply mode, compressor shutdown,
Four-way valve commutates, and compressor is opened, and heat pump unit recovers heating mode operation, and defrosting process terminates.From the above process,
Entire defrosting process, four-way valve commutates twice, compressor shuts down/starts shooting twice, heat pump unit stop to air-conditioned room heat supply 5~
10 minutes, room temperature is caused to fluctuate big, thermal comfort and is difficult to ensure that.
In conclusion how to solve the problem that prior art is using reverse cycle defrosting, become art technology
Personnel's urgent problem to be solved.
