The invention provides a rapid defrosting device of an air conditioner. The rapid defrosting device of the air conditioner comprises an air conditioner external unit shell, an expansion valve, a copper pipe, a compressor and fins, wherein the copper pipe is inserted into the fins arranged in parallel in the manner of U shape to form a heat exchanger of an air conditioner external unit; both ends of the copper pipe are respectively connected with one end of the compressor and one end of the expansion valve; the copper pipe at the other end of the expansion valve passes through the interior of a heat-storage thermal-insulation tank; a working medium is filled in the heat-storage thermal-insulation tank; a heat conduction pipe is also inserted into the fins; the heat conduction pipe forms an independent loop in the fins; a pump body is arranged in the loop; the pump body is electrically connected with an air conditioner defrosting control circuit; heat conduction oil is filled in the heat conduction pipe; and the heat conduction pipe passes through the interior of the heat-storage thermal-insulation tank. According to the rapid defrosting device of the air conditioner, rapid defrosting can be realized on the air conditioner without switching operating modes, thereby, a great amount of electric energy is saved.
Description
Affiliated technical field
The present invention relates to air-conditioning auxiliary equipment field, especially, is a kind of air-conditioning quick defrosting apparatus.
Background technology
Under the pattern that heats, what outdoor machine of air-conditioner blew is cold wind, and heat exchange temperature is in subzero several years or 10 several years, and the steam in this moment outside air is dewfall on the machine fin outside, then is frozen into ice cube.If do not defrost, outer machine is blocked by ice cube, can't dispel the heat, and ice cube is tied thicker and thicker, and refrigerant can't evaporate in the final outer machine, hypotony, and low-voltage variation is jumped by system, shuts down.After reaching certain condition (every kind of air-conditioning dispatches from the factory and sets: be lower than environment temperature X ° and lasting X minute like the fin temperature); Begin defrosting, this moment, system changed into refrigeration mode, and cross valve is with inside and outside machine exchange function; Refrigerant is a HTHP freon in the outer machine; Melt ice cube, reached the back defrosting that imposes a condition and finish, be replaced by refrigeration mode.
Through the running refrigerating pattern with indoor a part of heat as the ice cube that melts on the off-premises station fin, frequent switching start and stop compressor has expended a large amount of electric energy, when defrosting simultaneously, the indoor temperature fall is also bigger, brings sense of discomfort to the people.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of air-conditioning quick defrosting apparatus, this device makes air-conditioning need not switching working mode, and just the ability quickly defrosting is practiced thrift a large amount of electric energy.
The technical solution adopted for the present invention to solve the technical problems is: this air-conditioning quick defrosting apparatus comprises outdoor machine of air-conditioner shell, expansion valve, copper pipe, compressor and fin; Said copper pipe interts the heat exchanger of forming outdoor machine of air-conditioner into the fin that is arranged in parallel with the mode of " U " type; The two ends of said copper pipe connect compressor one end and expansion valve one end respectively, and it is inner that the copper pipe of the other end of said expansion valve passes a heat-storage heat-preserving jar, and said heat-storage heat-preserving jar inside is full of working medium; Also be interspersed with another heat pipe on the said fin; Said heat pipe forms independent loop in fin, and is provided with the pump housing in the said loop, and the said pump housing and air-conditioner defrosting control circuit are electrically connected; The inner falling heat-transfer oil of said heat pipe, it is inner that said heat pipe passes said heat-storage heat-preserving jar.
As preferably, said working medium is phase-change material.
As preferably, the part body that said heat pipe and said copper pipe are in the heat-storage heat-preserving jar is provided with heat exchanger fin.
The invention has the advantages that:
When utilizing working medium to store operation of air conditioner, the fraction heat that is absorbed is used for defrostingization ice, avoids switching working mode when making air-conditioner defrosting, has practiced thrift electric energy.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this air-conditioning quick defrosting apparatus.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Shown in Figure 1 is the planform sketch map of an embodiment of this air-conditioning quick defrosting apparatus.
In the present embodiment; This air-conditioning quick defrosting apparatus comprises outdoor machine of air-conditioner shell 1, expansion valve 5, copper pipe 2, compressor 3 and fin 21, and said copper pipe 2 interts the heat exchanger of forming outdoor machine of air-conditioner 1 into the fin that is arranged in parallel 21 with the mode of " U " type, and the two ends of said copper pipe 2 connect compressor 3 one ends and expansion valve 5 one ends respectively; The copper pipe 2 of the other end of said expansion valve 5 passes a heat-storage heat-preserving jar 41 inside; Said heat-storage heat-preserving jar 41 inside are full of working medium, also are interspersed with another heat pipe 4 on the said fin 21, and said heat pipe 4 forms independent loop in fin 21; And be provided with the pump housing 42 in the said loop; The said pump housing 42 is electrically connected with air-conditioner defrosting control circuit 101, said heat pipe 4 inner falling heat-transfer oil, and said heat pipe 4 passes said heat-storage heat-preserving jar 41 inside.
Said air-conditioner defrosting control circuit is the control circuit that common air-conditioning all adopts, and only needs when air-conditioner defrosting, gets final product for the pump housing 42 energisings.
Above-mentioned air-conditioning quick defrosting apparatus, said working medium is phase-change material, when phase-change material undergoes phase transition, can absorb and discharges a large amount of heats, helps quickly defrosting.
The part body that above-mentioned air-conditioning quick defrosting apparatus, said heat pipe 4 and said copper pipe 5 are in the heat-storage heat-preserving jar 41 is provided with heat exchanger fin 410, strengthens heat exchange efficiency, makes defrosting and heat accumulation speed faster.
The defrost process of above-mentioned air-conditioning quick defrosting apparatus is:
Air-conditioning is when normal operation; Phase-change material in the said heat-storage heat-preserving jar 41 absorbs the heat that the fraction air-conditioning heats, and when needs defrosted, air-conditioner defrosting control circuit 101 drove the pump housing 42; Through circulating heat conduction oil the heat that stores in the phase-change material in the heat-storage heat-preserving jar 41 is released on the fin 21; Defrost, avoid switching working mode when making air-conditioner defrosting, practiced thrift electric energy.
