In general, the main stream defrosting mode in the market adopts four defrosting schemes of electric defrosting, water defrosting, hot gas bypass defrosting and hot fluoride defrosting. The hot gas bypass defrosting and the hot fluoride defrosting are more energy-saving and are attractive in the market due to small fluctuation of the storage temperature. However, the hot gas bypass defrost mode is complicated by the necessity of having two or more evaporators and the need for a series of valves and discharge barrels to control the evaporators.
The hot fluoride cream can be changed by only reversing the four-way valve, so most people choose hot compress and defrost.

Referring to fig. 1, the present application provides a defrosting apparatus 100. The defrosting device 100 is used for defrosting a water pan, which is a chassis of an air conditioner. It is understood that the chassis is used for receiving condensed water generated during heat exchange of the heat exchanger and discharging the condensed water through the drain hole of the chassis. If the chassis frosts, the condensed water in the chassis cannot flow out. Therefore, the chassis needs to be defrosted to avoid frosting of condensed water in the chassis. Of course, in other embodiments of the present application, the defrosting device 100 may perform defrosting treatment on other members that are prone to frosting. The defrosting device 100 can realize defrosting of the chassis without adding a four-way valve, thereby reducing the cost of the defrosting device 100 and further reducing the cost of the whole air conditioner.
In one embodiment, defrosting apparatus 100 includes heat absorbing assembly 110 and heat transferring assembly 120. The heat absorbing assembly 110 is used for absorbing heat. The heat transfer assembly 120 is connected to the heat absorbing assembly 110, and is disposed on the chassis of the air conditioner, for transferring heat of the heat absorbing assembly 110 to the chassis. After the heat absorbing component 110 absorbs heat, the heat can be transferred to the heat transfer component 120, and the heat transfer component 120 can exchange heat with the chassis to transfer the heat to the chassis, so as to defrost the chassis.
It will be appreciated that the source of heat from the heat sink assembly 110 is in principle not limited so long as the operation of the air conditioning system is not affected. The heat sink assembly 110 absorbs heat from the ambient environment, may also absorb heat from the compressor during operation, and may also absorb heat from the compressor discharge, as described in more detail below. In addition, the heat transfer component 120 heats the chassis by adopting a radiation heating mode, and can absorb the cold of the chassis, so as to defrost the chassis.
The defrosting device 100 can realize defrosting of the chassis through heat absorption and heat transfer of the heat absorption component 110 and the heat transfer component 120 without adding a four-way valve, so that the problem of high cost caused by defrosting of the chassis due to inflow of a refrigerant when the four-way valve is adopted for reversing at present can be effectively solved, the cost of the defrosting device 100 is reduced, and the cost of the whole air conditioner is further reduced.
In one embodiment, the heat absorbing assembly 110 is coupled to the discharge pipe of the compressor for absorbing heat from the gas in the discharge pipe when the compressor is discharging. That is, the source of heat absorbed by the heat sink assembly 110 is the mixture of oil and gas at the compressor discharge. When the compressor is exhausted, the oil-gas mixture has higher temperature, and after the heat absorbing component 110 absorbs the heat of the oil-gas mixture, the operation of the compressor is not influenced, and meanwhile, the heat can be fully utilized, so that the purposes of energy conservation and consumption reduction are achieved, and the cost is reduced. The heat absorbing assembly 110 may absorb heat of the mixture of oil and gas in the compressor discharge pipe and transfer the heat to the heat transfer assembly 120, and the chassis is heated by the heat transfer assembly 120 to defrost the chassis.
In one embodiment, the heat sink assembly 110 includes a heat sink container 111 having a closed cavity, wherein the heat sink container 111 is in communication with the heat transfer assembly 120, and wherein a saturated liquid is contained in the heat sink container 111 that is vaporized and condensed by cooling. The saturated liquid in the heat absorbing container 111 can be vaporized into steam after absorbing heat and then enters the heat transfer component 120, the heat transfer component 120 heats the chassis, so that the chassis is defrosted and simultaneously absorbs the cold energy of the chassis, and the steam in the heat transfer component 120 is condensed into saturated liquid after precooling and flows back to the heat absorbing container 111. The heat absorbing container 111 with the closed cavity can avoid the escape of the vaporized saturated liquid, so that the saturated liquid in the heat absorbing component 110 can be recycled, the repeated addition of the saturated liquid is avoided, and the cost is saved.
As shown in fig. 1, wherein a is a saturated liquid in the liquid state. In order to save cost, the saturated liquid may be a refrigerant, and the refrigerant is directly injected into the heat absorbing container 111. The refrigerant is vaporized to form a gaseous refrigerant after being heated, and the gaseous refrigerant can be condensed into a liquid refrigerant after being cooled. Of course, in other embodiments of the present application, the saturated liquid may also be a liquid that is vaporized by heating, pre-cooled, condensed, such as ethylene glycol, brine, or the like.
Optionally, the heat absorbing container 111 is sleeved on the exhaust pipe of the compressor. That is, the heat absorbing container 111 is sleeved outside the exhaust pipe. The exhaust pipe absorbs heat of the oil-gas mixture and then directly transfers the heat to the saturated liquid in the heat absorbing container 111. This requires that the heat absorbing container 111 is hollow, and the heat absorbing container 111 is sleeved on the exhaust pipe, and then the outer wall of the exhaust pipe is abutted against the hollow inner wall of the heat absorbing container 111, so as to ensure that the heat of the exhaust pipe can be directly transferred into the saturated container of the heat absorbing container 111, and ensure that the sufficient heat absorbed by the saturated container is vaporized. Of course, the outer wall of the exhaust pipe and the hollow inner wall of the heat absorbing container 111 may be integrally formed.
However, the mounting of the exhaust pipe and the heat absorbing container 111 in the above manner may result in complicated operations. Therefore, in an embodiment, the heat absorbing assembly 110 further includes a vent pipe 112, the vent pipe 112 penetrates through the heat absorbing container 111, and the outer wall of the vent pipe 112 and the heat absorbing container 111 enclose a closed cavity, and two ends of the vent pipe 112 are respectively connected to the exhaust pipe of the compressor. That is, the discharge pipe of the compressor is divided into two sections, and when the compressor is installed, both ends of the ventilation pipe 112 are connected to the two sections of the discharge pipe of the compressor. In this way, the installation of the defrosting device 100 and the exhaust pipe can be facilitated, and the assembly efficiency can be improved. Preferably, the two ends of the vent pipe 112 are of joint structures, so that the vent pipe is convenient to connect with an exhaust pipe.
When the compressor exhausts, after the oil-gas mixture passes through the exhaust pipe and the vent pipe 112, the vent pipe 112 can absorb heat of the oil-gas mixture and transfer the heat to saturated liquid in the closed cavity, so that the saturated liquid is heated and vaporized. The outer wall of the vent pipe 112 and the inner wall of the heat absorbing container 111 can enclose a closed cavity with a closed cross section, so that the vent pipe 112 can directly saturate the heat with liquid after being heated, thereby avoiding heat loss and improving the heat utilization rate.
Moreover, the shape of the heat absorbing container 111 is not limited in principle as long as it can hold a combination of saturated liquids. In this embodiment, the heat absorbing container 111 is in a spheroid shape, and two ends of the heat absorbing container 111 are flat surfaces. Of course, in other embodiments of the present application, the cross-sectional shape of the heat absorbing container 111 may be square, oval, polygonal, irregular, or the like.
In one embodiment, the surface area of the inner wall of the vent tube 112 is greater than the surface area of the outer wall of the vent tube 112. Therefore, the contact area of the vent pipe 112 and the oil-gas mixture discharged by the compressor can be increased, so that the heat absorption effect of the vent pipe 112 under the same flow is better, more heat is ensured to heat saturated liquid, and the defrosting effect is improved. Optionally, the inner wall of the vent pipe 112 has a plurality of protrusions thereon, and the protrusions increase the surface area of the inner wall of the vent pipe 112. In this embodiment, the ventilation pipe 112 may also be an internally threaded pipe, and the external boiling heat exchange and the heat transfer resistance are concentrated on the inner side. Of course, other structures for increasing the surface area of the inner wall may be employed for the vent tube 112.
In an embodiment, the heat transfer assembly 120 includes a first connection pipe 121, a heat exchange pipe 122 and a second connection pipe 123 sequentially connected, the heat exchange pipe 122 is disposed on the chassis and exchanges heat with the chassis, the first connection pipe 121 and the second connection pipe 123 are further communicated with the heat absorption container 111, the first connection pipe 121 is used for outputting saturated liquid vaporized in the heat absorption container 111, and the second connection pipe 123 is used for refluxing saturated liquid condensed by the heat exchange pipe 122. One end of the first connection pipe 121 is connected to the heat absorbing container 111, the other end of the first connection pipe 121 is connected to the heat exchange pipe 122, the heat exchange pipe 122 is further connected to one end of the second connection pipe 123, and the other end of the second connection pipe 123 is connected to the heat absorbing container 111.
And, the connection of the first connection pipe 121 and the heat absorbing container 111 is higher than the connection of the second connection pipe 123 and the heat absorbing container 111, so that the first connection pipe 121 communicates with a space above the saturated liquid of the heat absorbing container 111, and the second connection pipe 123 communicates with a space having the saturated liquid of the heat absorbing container 111. That is, the first connection pipe 121, the heat exchange pipe 122, and the second connection pipe 123 form a circulation line. The first connection pipe 121 may transmit the saturated liquid vapor in the heat absorption vessel 111 to the heat exchange pipe 122, and the second connection pipe 123 may transmit the saturated liquid condensed by the heat exchange pipe 122 back to the heat absorption vessel 111. In this way, the vapor formed after the saturated liquid is vaporized may enter the heat exchange tube 122 through the first connecting tube 121, and after the heat exchange tube 122 heats the chassis, the vapor in the vapor condenses into saturated liquid, and flows back to the heat absorbing container 111 through the second connecting tube 123, so that the frost of the chassis is melted conveniently.
The heat exchange tube 122 exchanges heat with the chassis, and after the heat of the heat exchange tube 122 is transferred to the chassis, the cold of the chassis is absorbed and condensed into saturated liquid by the steam in the heat exchange tube 122. Continuous defrosting operation of the chassis is realized through vaporization, condensation, re-vaporization and re-condensation of saturated liquid, and the chassis is prevented from frosting in a low-temperature environment, so that condensed water in the chassis can be timely discharged. Alternatively, the heat exchange tube 122 is made of a tube with better heat exchange, such as a copper tube. Therefore, the heat exchange effect can be ensured, and the defrosting effect of the chassis is further ensured.
In one embodiment, the heat exchange tube 122 is bent and arranged on the chassis, and the heat exchange tube 122 is bent at least once. Thus, the number of loops of the heat exchange tubes 122 arranged on the chassis can be increased, the heat exchange area of the heat exchange tubes 122 and the chassis is increased, the heat exchange effect of the heat exchange tubes 122 and the chassis is further improved, and the defrosting effect of the chassis is further improved. Further, the diameter of the heat exchange tube 122 ranges from 3mm to 10mm. That is, a larger specific surface area, i.e., an equivalent area, can be achieved with finer tubing, with more heat exchange tubes 122 being disposed, increasing heat transfer. By way of example, the heat exchange tube 122 may have a diameter of 6mm.
In one embodiment, the heat exchange tube 122 is disposed obliquely to the chassis. It can be understood that the chassis is obliquely arranged when being arranged, so that condensed water in the chassis can flow out through the drain holes of the chassis. Accordingly, the inclined arrangement of the heat exchange tube 122 can ensure the heating effect of the heat exchange tube 122 on the chassis, thereby improving the defrosting effect. It is understood that the heat exchange tube 122 may be located below the chassis, above the chassis, or above and below the chassis. Moreover, after the heat exchange tube 122 is obliquely arranged, the condensed saturated liquid in the heat exchange tube 122 is further convenient to flow back to the second connecting tube 123, so that the condensed saturated liquid is convenient to flow back to the heat absorbing container 111, and the saturated liquid is prevented from accumulating in the heat exchange tube 122. Optionally, the heat exchange tube 122 has an inclination angle equal to 3 ° in order to facilitate the reflux of saturated liquid.
In one embodiment, the saturated liquid in the absorber vessel 111 occupies 1/3 to 2/3 of the volume of the absorber vessel 111. This ensures that the amount of saturated liquid is sufficient to effect defrosting of the chassis. It can be appreciated that the amount of saturated solution is calculated by multiplying the condensation amount of steam in the heat exchange tube 122 per unit time by the vaporization latent heat of the condensed liquid according to the power of the chassis defrosting, so as to satisfy the heat required by the chassis defrosting of different sizes and ensure the heat exchange effect of the chassis.
In one embodiment, the heat sink assembly 110 is of unitary construction with the heat transfer assembly 120. Thus, the connection reliability can be ensured, and the assembly process can be reduced. The ventilation pipe 112 is integrally formed with the heat absorbing container 111. Thus, the connection reliability can be ensured, and the assembly process can be reduced. The first connection pipe 121, the heat exchange pipe 122, and the second connection pipe 123 are integrally formed. Thus, the connection reliability can be ensured, and the assembly process can be reduced.
The defrosting apparatus 100 of the present application melts frost of the chassis using the rising latent heat of steam. Specifically, when the air conditioner is operated at a low temperature, the exhaust pipe of the compressor discharges a high-temperature oil-gas mixture, the air pipe 112 absorbs heat of the oil-gas mixture and then transfers the heat to saturated liquid in the heat absorption container 111, so that the saturated liquid is vaporized into steam, the steam rises to enter the heat exchange pipe 122 through the first connecting pipe 121, and exchanges heat with the chassis through the heat exchange pipe 122 to heat the chassis, meanwhile, the steam in the heat exchange pipe 122 absorbs cold of the chassis to form saturated liquid, and flows back to the second connecting pipe 123 and then flows back to the heat absorption container 111, so that the whole heat transfer cycle is completed.
The application also provides an air conditioner, which comprises a chassis and the defrosting device 100 in the embodiment. After the defrosting device 100 is adopted by the air conditioner, the defrosting of the chassis can be realized, a four-way valve is not required to be added, the cost is reduced, and the heat utilization rate is improved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be regarded as the description scope of the present specification.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
