Description

Technical Field

[0001] The utility model relates to the technical field of condensation heat recovery, in particular to an air-conditioning condensation heat recovery energy-saving device. Background Art

[0002] The working principle of air conditioning refrigeration is that the compressor compresses refrigerants such as Freon, adding high temperature and high pressure properties. After being cooled by the condenser, relatively low temperature and high pressure Freon is formed. After the high pressure Freon is depressurized by the expansion valve, it expands and evaporates, further lowering the temperature and absorbing the surrounding temperature. This part of the pipeline is set at the air outlet of the air conditioner indoor unit to cool the incoming air. After that, the low temperature and low pressure Freon re-enters the compressor for compression.

[0003] The current condenser uses an air cooling system to cool the high-temperature and high-pressure Freon in the tube coil. This part of the temperature is directly dissipated without being effectively recycled, resulting in a certain amount of energy waste. At the same time, the condensed water formed by cooling the air at the air outlet is also directly discharged. Both this part of heat and condensed water have recycling value. Therefore, the utility model proposes a structure that combines the condensed water and condensation heat for recovery. Utility Model Content

[0004] The purpose of the present invention is to provide an air-conditioning condensing heat recovery and energy-saving device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An air conditioning condensation heat recovery and energy-saving device, comprising:

[0007] A device housing, the device housing including an air outlet pipe, the air outlet pipe being designed as a spiral structure;

[0008] The temperature recovery system comprises a heat absorbing shell, wherein an air outlet pipe is wrapped and buried inside the heat absorbing shell.

[0009] Further, the device housing further comprises:

[0010] A base, wherein a heat-insulating shell is fixedly mounted on the edge of the upper surface of the base;

[0011] The temperature recovery chamber is opened inside the heat-insulating shell, and the heat-absorbing shell is fixedly installed inside the temperature recovery chamber.

[0012] Further, the device housing further comprises:

[0013] A compressor, wherein the compressor is fixedly mounted on the upper surface of the heat-insulating shell, the lower edge of the side surface of the compressor is connected to one end of the air outlet pipe, and the other end of the air outlet pipe protrudes from the lower edge of the outer side of the heat-insulating shell;

[0014] An air return pipe, one end of which is communicated with the top of the compressor, and the other end of which passes through the base and protrudes from one side of the base.

[0015] Furthermore, the temperature recovery system further comprises:

[0016] The heat-conducting fins are arranged in two groups, each group having a plurality of heat-conducting fins, and the two groups of heat-conducting fins are arranged in a circular manner at equal angles and fixedly mounted on both sides of the outer surface of the heat-absorbing shell;

[0017] The condensed water conduit passes through the two groups of heat-conducting fins, and both ends of the condensed water conduit protrude from the upper side of the heat-insulating shell.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The outlet pipe is used as the condensation pipeline. The high-temperature and high-pressure gaseous Freon compressed by the compressor is passed into the wound outlet pipe. The heat-absorbing shell is made of heat-conducting material and completely wraps the outlet pipe to absorb the high temperature released when the Freon is condensed. At the same time, the outlet pipe presents a loop-type pipeline in the heat-absorbing shell, forming two channels inside the heat-absorbing shell, which greatly increases the contact area between the outlet pipe and the heat-absorbing shell, improves the heat conduction effect, and collects the condensation heat generated when the Freon is cooled.

[0020] 2. The condensed water generated when the indoor unit of the air conditioner cools the air is directly passed into the condensed water duct after being recovered, and enters the temperature recovery system, and directly contacts with two sets of heat-conducting fins. The heat-conducting fins and the heat-absorbing shell form a heat exchange bridge between the condensed water duct and the outlet pipe, forming a water-cooling system, replacing the air-cooling structure of the traditional condenser, absorbing the heat inside the outlet pipe and taking it away. While cooling the Freon, the condensation heat is absorbed into the condensed water for recovery and storage. The condensed water is then guided by the condensed water duct to other structures for reuse of the condensed water and the condensation heat stored in the condensed water.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 In an embodiment of the utility model, an air-conditioning condensing heat recovery and energy-saving device includes a device housing 1 and a temperature recovery system 2. The device housing 1 includes an air outlet pipe 106, and the air outlet pipe 106 is designed to be a spiral structure; the temperature recovery system 2 includes a heat absorption shell 201, and the air outlet pipe 106 is wrapped and buried inside the heat absorption shell 201.

[0030] Specifically, the outlet pipe 106 is used as a condensation pipeline, and the high-temperature and high-pressure gaseous Freon compressed by the compressor 104 is passed into the inside of the wound outlet pipe 106. The heat absorption shell 201 is made of heat-conductive material and completely wraps the outlet pipe 106 to absorb the high temperature released when the Freon is condensed. At the same time, the outlet pipe 106 presents a loop-type pipeline in the heat absorption shell 201, and two channels are formed inside the heat absorption shell 201, which greatly increases the contact area between the outlet pipe 106 and the heat absorption shell 201, improves the heat conduction effect, and collects the condensation heat generated when the Freon is cooled.

[0031] Example 1

[0032] like Figure 1-2 As shown, in this embodiment, the device housing 1 also includes a base 101 and a temperature recovery chamber 103, and an insulation shell 102 is fixedly installed on the edge of the upper surface of the base 101; the temperature recovery chamber 103 is opened inside the insulation shell 102, and the heat absorption shell 201 is fixedly installed inside the temperature recovery chamber 103.

[0033] In this embodiment, the temperature recovery chamber 103 completely covers the temperature recovery system 2 and the air outlet pipe 106, restricting the natural dissipation of heat to a certain extent, so that the heat can only be absorbed and transferred by the heat absorption shell 201, thereby improving the recovery effect of condensation heat.

[0034] like Figure 1-4 As shown, in this embodiment, the equipment housing 1 also includes a compressor 104 and a return air pipe 105. The compressor 104 is fixedly mounted on the upper surface of the thermal insulation shell 102. The lower edge of the side surface of the compressor 104 is interconnected with one end of the outlet pipe 106, and the other end of the outlet pipe 106 protrudes from the lower edge of the outer side of the thermal insulation shell 102; one end of the return air pipe 105 is interconnected with the top of the compressor 104, and the other end of the return air pipe 105 passes through the base 101 and protrudes from one side of the base 101.

[0035] During specific implementation, the low-temperature, low-pressure Freon gas is sent into the compressor 104 through the return air pipe 105, compressed by the compressor 104 to form a high-temperature, high-pressure gas, and then the heat is guided away from the gas when passing through the outlet pipe 106 for cooling, forming a relatively low-temperature, high-pressure Freon, and finally passed into the indoor expansion valve for pressure relief and expansion to further cool it down.

[0036] Example 2

[0037] On the basis of the first embodiment, in order to supplement the specific method of recovering the heat of the Freon inside the outlet pipe 106 which is not mentioned in the first embodiment.

[0038] like Figure 1 、 5 As shown in Figure 6, in this embodiment, the temperature recovery system 2 also includes heat-conducting fins 202 and condensing water pipes 203. The number of heat-conducting fins 202 is two groups, and the number of each group is several. The two groups of heat-conducting fins 202 are arranged in a circular shape with equal angles and fixedly installed on the outer side surfaces of the heat-absorbing shell 201; the condensing water pipe 203 passes through the two groups of heat-conducting fins 202, and both ends protrude from the upper side of the heat-insulating shell 102.

[0039] During specific implementation, the condensed water generated when the air conditioner indoor unit cools the air is directly passed into the condensed water duct 203 after being recovered, and enters the temperature recovery system 2, and directly contacts the two sets of heat-conducting fins 202. The heat-conducting fins 202 and the heat-absorbing shell 201 form a heat exchange bridge between the condensed water duct 203 and the outlet pipe 106, forming a water cooling system, replacing the air-cooling structure of the traditional condenser, absorbing the heat inside the outlet pipe 106 and taking it away. While cooling the Freon, the condensation heat is absorbed into the condensed water for recovery and storage, and then the condensed water is guided by the condensed water duct 203 to other structures for reuse of the condensed water and the condensation heat stored in the condensed water.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
