Abstract
The utility model discloses an air source heat pump low-temperature heating auxiliary electric heating evaporator, which consists of an air conditioner compressor, a condenser, a liquid storage tank, a filter, an expansion valve and an evaporator in sequential connection, wherein an electric heating device is arranged in any position between an outlet of the condenser and an air inlet of the compressor. The air source heat pump low-temperature heating auxiliary electric heating evaporator has a principle that a coolant medium with mixed air and liquid is obtained in the low-temperature heating work state of the compressor, when the coolant medium flows through the electric heating evaporator to be heated, partial coolant liquid is evaporated to become air, the process is the primary evaporation, and then, the air enters the air source heat pump evaporator under the effect of the compressor. At the time, the air source heat pump evaporator absorbs heat from the air through the effect of a draft fan, so the coolant is evaporated for a second time in the evaporator. Because of the twice evaporation, the low-temperature air and liquid coolant medium are sufficiently evaporated, the evaporation efficiency is improved, sufficient coolant air is provided for the low-temperature heating of the air source heat pump compressor, and the normal stable heating of the compressor at low temperature is realized.
Description
Technical field:
The utility model belongs to a kind of air source heat pump, particularly a kind of air source heat pump low-temperature heating auxiliary electro-heat evaporimeter.
Background technology:
The operation principle of air source heat pump and air-conditioning is to utilize the characteristic of refrigerant medium low-temperature evaporation.By the air-introduced machine on the evaporimeter airborne heat is introduced evaporimeter; Making setting-in go in the evaporator fin refrigerant medium in the copper pipe absorbs airborne heat and evaporates; Make the liquid in the refrigerant gas liquid mixture be evaporated to gas entering compressor, the gas that produces HTHP through compressor compresses heats.This moment, high temperature and high pressure gas was commonly referred to as air-conditioning through the equipment that the condenser heat radiation produces hot blast; If this high temperature and high pressure gas is called air source heat pump again usually through the equipment of heat exchanger heat exchange generation hot water.Present air source heat pump and air-conditioning are lower than-5 ℃ and just can not normally heat in environment temperature.Its reason is: the heat that from air, absorbs of common air-conditioning evaporimeter is few at low temperatures; Needed capacity refrigerant tolerance when being not enough to evaporate compressor and normally heating; And can't reach condition and the requirement that compressor normally heats, therefore below low temperature-5 ℃, do not heat.
The utility model content:
The purpose of the utility model provides and a kind ofly can make the air source heat pump air source heat pump low-temperature heating auxiliary electro-heat evaporimeter that its air source heat pump still can operate as normal under low temperature condition.
To achieve these goals; The solution of the utility model is: a kind of air source heat pump low-temperature heating auxiliary electro-heat evaporimeter; Connected to form successively by compressor of air conditioner, condenser, fluid reservoir, filter, expansion valve, evaporimeter, said optional position between condensator outlet and compressor inlet is provided with electric heater unit.
Said this electric heater unit is to be made up of an internal heated type electric heated pipe, and the axle core of this electrothermal tube is provided with an electric heating tube, and being provided with around the axle core can be through the spiral gas passage of refrigerant.
Its principle is exactly after the gas after compression heats up under the duty of compressor low-temperature heating gets into condenser or heat exchanger heat exchange by blast pipe; Become the refrigerant medium of gas-liquid mixed;, it is heated when flowing through electric evaporator; Make part refrigerant liquid obtain evaporation and become gas, under the effect of compressor, get into air source heat pump evaporation device then for evaporating for the first time.This moment, air source heat pump evaporation device made refrigerant in evaporimeter, obtain evaporation again because the effect of air-introduced machine absorbs heat from air, and we claim evaporation, i.e. double-effect evaporation for the second time.Because twice evaporation evaporates the gas-liquid refrigerant medium low temperature under fully, improved evaporation performance, heat the cold media gas that capacity is provided at low temperatures to the air source heat pump compressor, thus realized compressor at low temperatures normal and stable heat.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model electric heater unit.
The specific embodiment
Like Fig. 1, shown in Figure 2; This air source heat pump low-temperature heating auxiliary electro-heat evaporimeter; Connected to form successively by compressor of air conditioner 2, condenser 1, fluid reservoir 3, filter 7, expansion valve 8, evaporimeter 3, said optional position between condensator outlet 5 and compressor inlet 4 is provided with electric heater unit 9.Said this electric heater unit 9 is to be made up of an internal heated type electric heated pipe, and the axle core of this electrothermal tube is provided with an electric heating tube 11, and being provided with around the axle core can be through the spiral gas passage 10 of refrigerant.
Said this electric heater unit 9 places the outside refrigerant of evaporimeter 3 main bodys through on the pipeline, and the refrigerant in the heating spiral pipeline is called the external-heat electric evaporator.
Spiral pipeline on the vaporizer body, can be with metal tube and ring on vaporizer body, also can on vaporizer body, be processed into screw type refrigerant pipe.
Electric evaporator is to utilize the small power electric heater to heat the cold media gas that passes through in the helical form pipeline.Also, system's device of air source heat pump evaporation for the second time evaporates the condition of having created from air through the electrical heating evaporation first time for absorbing heat.Use low power heater that the about 3500 watts of compressors of 5P machine can normally be heated at low temperatures, played the amplification of evaporation power.The electric heating evaporation device has heated the refrigerant in the system when compressor start, help the compressor cold-starting.
