Description

Technical Field

[0001] The utility model belongs to the technical field of water heater equipment, in particular to a waste heat recovery air-conditioning water heater. Background Art

[0002] The air conditioning equipment in the prior art has similar structural principles, but the final use mode and the specific pipe design and connection are different. In the pipe design, reducing costs will undoubtedly win greater competitive space for enterprises. The air conditioner and water-making equipment in the prior art are still separate. The condensation heat is discharged to the outside and discarded during air conditioning cooling, which is not fully utilized, resulting in energy waste to a certain extent. At present, in the field of air conditioning, the main research direction of scientific researchers is easy installation and use, small comprehensive investment, energy saving, and high thermal efficiency. Summary of the invention

[0003] The utility model provides a waste heat recovery air-conditioning water heater, so as to achieve the purpose of reducing production cost and having strong practicality.

[0004] A waste heat recovery air conditioning water heater, characterized in that it includes a compressor, an evaporator, an air conditioner and a water tank;

[0005] A valve 1 is provided on the pipe 1 connecting the compressor and the evaporator; a throttle valve is provided on the pipe 2 connecting the evaporator and the air conditioner; the air conditioner is connected to the liquid storage tank to the compressor through the pipe 3;

[0006] On pipeline two, between the evaporator and the throttle valve, there is connected pipeline four, which is connected to the water tank;

[0007] Pipeline 5 is also connected to pipeline 1 between the compressor and valve 1, and pipeline 5 is connected to the water tank. Valve 2 is arranged in pipeline 5.

[0008] Furthermore, the valve one and valve two are solenoid valves respectively.

[0009] Beneficial effects of the utility model:

[0010] 1. In the air conditioning heat pump system in the prior art, a four-way valve is often used. This system does not use a four-way reversing valve, thereby avoiding the failure caused by the four-way valve, as follows:

[0011] 1. Avoid the failure caused by the four-way valve not reversing.

[0012] 2. Avoid insufficient flow, that is, the four-way valve does not switch to the right position, the main slide valve stops in the middle position, and the next time it is started, the flow is insufficient due to the effect of the middle flow.

[0013] 3. Avoid poor commutation.

[0014] 4.Avoids the risk of cross-gas.

[0015] 2. In the system of the utility model, the operating mode does not have an air-conditioning-only heating mode nor a water tank-only hot water mode, and is more practical, as follows.

[0016] 1. The price is cheap. The same brand and the same type of machine can be at least a thousand yuan cheaper than setting the air conditioner to heating mode only.

[0017] 2. Low maintenance rate. The pipeline connection design is simpler and fewer valves are used, so the technical difficulty is lower and relatively fewer intelligent components are used, so there are very few failures and the maintenance rate is naturally reduced.

[0018] In addition, the waste heat recovery air-conditioning water heater of the utility model is used in tropical areas where air-conditioning and refrigeration are required all year round. The product equipment cost is low, energy is recycled and utilized, and energy consumption is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
