Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a new exhaust condensation heat recovery air conditioning unit for condensed water reuse. Background Art

[0002] The condensing exhaust heat recovery fresh air unit consists of four parts: fresh air system, exhaust system, return air system and heat recovery system. Among them, the fresh air system consists of fresh air fan, fresh air duct, fresh air valve, etc.; the exhaust system consists of exhaust fan, exhaust duct, exhaust valve, etc.; the return air system consists of return air duct and return air valve, etc.; the heat recovery system mainly consists of heat exchanger and circulating water pipeline, etc.

[0003] The operation process of the condensing exhaust heat recovery fresh air unit mainly includes the following parts: first, the exhaust system discharges the indoor exhaust gas, and at the same time transfers the energy in the exhaust gas to the outside through the exhaust fan. Secondly, the fresh air system draws the outside air into the room through the fresh air fan, and at the same time transfers the energy in the fresh air to the room. Then, the heat recovery system starts to work, and the circulating water runs through the heat exchanger of the fresh air and the exhaust air, and the energy in the fresh air and the energy in the exhaust air are exchanged, avoiding the heat energy loss between the fresh air system and the exhaust system. Finally, the return air system recovers part of the indoor exhaust gas through the return air valve, and at the same time transfers the energy in the return air to the room.

[0004] At present, in the actual use of new exhaust condensation heat recovery air conditioning units, condensed water is directly discharged through the drainage pipe, which does not have the function of condensed water recycling. Directly discharging condensed water is likely to cause waste of water resources, and condensed water will flow to the side of the air conditioning unit, thereby polluting the surrounding environment. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a new exhaust condensation heat recovery air conditioning unit for condensed water reuse, so as to solve the current technical problem that the condensed water is not recycled and utilized, and the condensed water is directly discharged, which easily causes a waste of water resources.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a new exhaust condensation heat recovery air conditioning unit for condensed water reuse, including:

[0007] The air conditioning unit body and the single chip microcomputer fixedly mounted on one side wall of the air conditioning unit body, the one side wall of the air conditioning unit body is fixed with a water storage mechanism, and the water storage mechanism includes:

[0008] A water storage tank is installed on one side wall of the air conditioning unit body, a drainage pipe is fixedly connected to the upper side of one side wall of the air conditioning unit body, the outer end of the drainage pipe passes through the top of the water storage tank, a liquid level meter is fixed on one side wall of the water storage tank, the signal output end of the liquid level meter is connected to the signal input end of the single chip microcomputer, and the signal output end of the single chip microcomputer is connected to the signal input end of the liquid pump;

[0010] In actual use, the condensed water of the air-conditioning unit body is discharged into the water tank through the drain pipe for accumulation. As the water level in the water tank rises, the liquid level meter can feed back the water level information to the single-chip microcomputer.

[0014] The signal output terminal of the single chip microcomputer is connected to the signal input terminal of the servo motor;

[0015] In actual use, one of the filter cartridges is aligned with the drain pipe, so that when the condensed water enters the water tank, the filter cartridge can be used to filter the condensed water to remove impurities in the water, thereby avoiding the condensed water from being reused and preventing impurities from entering the equipment and causing impact. In addition, the user can periodically start the servo motor to drive the turntable to rotate a certain angle, so that another filter cartridge can be replaced for filtering, thereby avoiding blockage of a single filter cartridge affecting the filtering effect, thereby extending the cleaning cycle.

[0016] Preferably, a threaded column is fixed to the tail end of the filter cartridge, and the threaded column is threadedly engaged with the inner wall of the threaded cartridge, so that the filter cartridge is easy to disassemble and assemble, thereby facilitating its disassembly and cleaning.

[0017] Preferably, a through hole is opened on one side of the top of the water storage tank and an end cover is detachably connected to the through hole.

[0018] Preferably, a base is fixed to the bottom of the air conditioning unit body, and the arrangement of the base makes the device more stable as a whole.

[0020] 1.

The condensed water is used to supplement the circulating water, thereby avoiding the waste of water resources and achieving the effect of energy saving.

[0021] 2. The utility model provides a plurality of evenly distributed filter cartridges in the water storage tank, so that the condensed water is filtered by the mesh cylinder, thereby removing impurities and preventing the impurities from entering the circulating water tank and affecting the inside of the equipment. The filter cartridges can be automatically replaced regularly. The use of multiple filter cartridges can extend the cleaning cycle, thereby reducing the frequency of cleaning. At the same time, the end cover can be directly removed for cleaning, and the filter cartridge can be rotated to take out and clean. The cleaning does not affect the continuity of water storage and filtration, thereby improving the use effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS
