Problems solved by technology
At present, air source heat pumps and air conditioners cannot heat normally when the ambient temperature is lower than -5°C
The reason is: at low temperature, the ordinary air conditioner evaporator absorbs less heat from the air, which is not enough to evaporate the sufficient amount of refrigerant gas required by the compressor for normal heating, and cannot meet the conditions and requirements of the normal heating of the compressor. , so there is no heating at low temperatures below -5°C

The invention discloses an auxiliary low-temperature heating self-heating evaporator of an air-source heat pump, which consists of an air conditioner compressor, a condenser, a liquid storage tank, a filter, an expansion valve and an evaporator, wherein an auxiliary self-heating evaporator is arranged on an upper shell in an air conditioner compressor body, a helical coolant passage is helically arranged inside the auxiliary self-heating evaporator, an air inlet of the helical coolant passage is communicated with an outlet of the evaporator, and an air outlet of the coolant helical passage is communicated with an air inlet of the compressor. By adopting the auxiliary low-temperature heating self-heating evaporator, the self-heating evaporator is additionally installed on an ordinary air conditioner heat pump, and the heat produced by the compressor when in work is used for the air conditioner compressor to heat sufficient coolant gas under the low-temperature condition. The geological restriction of the air-source heat pump and the air conditioner heat supply and heating can be broken through, and a wide application prospect can be realized.
Description
technical field [0001] The invention belongs to an air source heat pump, in particular to an air source heat pump low-temperature heating auxiliary self-heating evaporator. Background technique [0002] The working principle of air source heat pump and air conditioner is to use the characteristics of low temperature evaporation of cold medium. The heat in the air is introduced into the evaporator by the induced fan on the evaporator, so that the refrigerant medium embedded in the copper tube in the fin of the evaporator absorbs the heat in the air and evaporates, so that the liquid in the refrigerant gas-liquid mixture evaporates The gas enters the compressor, and is compressed by the compressor to generate high-temperature and high-pressure gas for heating. At this time, the equipment where the high-temperature and high-pressure gas is dissipated by the condenser to generate hot air is generally called an air conditioner; if the high-temperature and high-pressure gas is ex...
