Description
Technical field
It the utility model is related to a kind of supplying hot water and heating plant, more particularly to a kind of air-source heat with defrost pipe
Pump.
Background technology
Air source heat pump is a kind of new hot water and heating installation using air-source as the energy, is a kind of alternative fire coal
The heating equipment and hot-water supply of boiler, have the characteristics that small, energy-efficient, environmentally protective, its principle is from compression
The high-temperature high-pressure refrigerant gas of machine compression gets in heat exchanger, after carrying out heat exchange with the cold water in heat exchanger, will exchange heat
Cool water heating in water tank, the gas refrigerant of high temperature and pressure are condensed into the liquid refrigerant of cryogenic high pressure, outflow heat exchanger warp
Enter evaporation in outdoor evaporator fin after crossing throttle valve throttling, air flows through outdoor evaporator fin, refrigerant by wind turbine
Forced heat-exchanging is carried out with air, refrigerant flashes to the gas of low-temp low-pressure, into compressor, reaches water heating after circulation compression
Purpose.
In southern area, winter outdoor temperature is generally not less than subzero 5 DEG C, and indoor calorific requirement is little, air source heat pump work
Well, efficiency is high.But it is very low in northern area winter outdoor temperature, the temperature of evaporator surface be usually reduced to zero degree with
Under, outdoor air flow through evaporator it is cooled when its contained by moisture can separate out and depend on evaporator surface and form frost layer, frost
The formation of layer increases the heat transfer resistance of evaporator, and evaporator temperature declines, and the economy of air source heat pump reduces.
At present, frequently with setting heating tube on evaporator fin with to the regular defrost of evaporator, the water formed after defrost
Drip and fallen into along fin in the drip tray of lower section, discharged from the drainpipe of drip tray side（As shown in Figure of description 5）, but
It is that, since the temperature of winter drip tray is also very low, the water in drip tray often forms white water, and is unfavorable for the discharge of low temperature frost water.
Utility model content
The purpose of this utility model is to provide a kind of air source heat pump with defrost pipe, after defrosting water is flowed into drip tray
Secondary frosting is not easy, so as to be conducive to the discharge of defrosting water.
The above-mentioned technical purpose of the utility model technical scheme is that：It is a kind of with defrost pipe
Air source heat pump, including compressor, condenser, primary throttle valve and evaporator fin, the condenser by refrigerant pipe successively
Connect compressor, evaporator fin and primary throttle valve, the evaporator fin bottom are provided with drip tray, the condenser and master
The defrost pipe passed through for refrigerant is communicated between throttle valve, the defrost pipe is layed in the bottom that drip tray deviates from evaporator fin
Portion, the outer wall of the defrost pipe and the bottom of drip tray are inconsistent.
Further, the defrost pipe is the spiral coil for hovering above water receiving tray bottom.
Further, the protective cover for alleviating the loss of defrost tubular heat is provided with the drip tray.
Preferably, described protective cover one end is hinged with drip tray, and protective cover one end opposite with hinged end is provided with
For the adjusting mechanism being detachably fixed protective cover on drip tray.
Preferably, the adjusting mechanism include being wholely set on the buckle and protective cover that are fixedly connected on drip tray with
It is buckled to occlusion or the grab departed from.
Further, it is provided with thermal insulation board on the inside of the protective cover.
In conclusion the utility model has the advantages that：
By connecting the defrost pipe for supplying refrigerant to pass through between heat exchanger and throttle valve, defrost pipe is laid with and contradicts in water receiving
The bottom of disk so that the refrigerant of the warm after over-heat-exchanger and cold water heat exchange on the one hand can be utilized to heat drip tray,
So that the cold water flowed into drip tray is not easy frosting, defrosting water is set smoothly to flow into drainpipe discharge；On the other hand, warm is cold
Heat in matchmaker further reduces after carrying out heat exchange by defrost Guan Shiyu drip trays, realizes time condensation process, improves
The degree of supercooling and evaporation break of refrigerant are poor, increase refrigerating capacity, so as to improve the refrigeration effect of refrigerant；
The heat exchange of defrost pipe and cold air in environment is improved by the setting of protective cover, is used for more heats
With cold water tray heat exchange；
Mutually fasten or depart from by buckle on grab on protective cover and drip tray, easily protective cover is dismantled or
Installation.
