Description

Technical Field

[0001] The utility model belongs to the technical field of water heater equipment, in particular to a heat pump air-conditioning hot water system with a simple structure. Background Art

[0002] In the prior art, air conditioners are usually installed in homes for heating or cooling; and hot water needs to be heated by solar water heaters, gas water heaters, electric water heaters, and boilers; since air conditioners and heat pump water heaters have the same operating principle, they are often started and run at the same time in homes. However, the energy generated by the two can be complementary under certain conditions, but this part of the energy is not effectively utilized, resulting in a significant increase in building energy consumption. Therefore, how to effectively integrate air conditioners and heat pump water heaters has become an urgent problem to be solved. Summary of the invention

[0003] The utility model provides a heat pump air-conditioning hot water system with a simple structure, so as to achieve the purposes of convenient assembly and reliable operation.

[0004] A heat pump air conditioning and hot water system with a simple structure, characterized in that it includes a compressor, an air conditioner and a water tank;

[0005] The pipeline connecting the compressor and the water tank is provided with an oil separator, a pressure switch and a one-way valve; the pipeline from the water tank to the air conditioner is provided with a straight-through valve, a throttle valve and a one-way valve; the pipeline from the air conditioner to the liquid storage tank to the compressor is provided with a three-way liquid injection valve and a pressure relief valve.

[0006] Furthermore, the three-way injection valve, one-way valve, straight-through valve and one-way valve are all installed in a threaded connection manner.

[0007] Beneficial effects of the utility model:

[0008] 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:

[0009] 1. Avoid the failure caused by the four-way valve not reversing.

[0010] 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 intermediate flow.

[0011] 3. Avoid poor commutation.

[0012] 4.Avoids the risk of cross-gas.

[0013] 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.

[0014] 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.

[0015] 2. Low maintenance rate. The pipeline connection design is simpler and uses fewer valves, 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.

[0016] 3. In this system, in terms of pipeline design and valve use, solenoid valves are not used, and relatively simple valves are used, which will reduce the failure rate; three-way injection valves, one-way valves, straight-through valves, and one-way valves can all be installed by threaded connection, making pipeline connection simpler and more convenient.

[0017] The use of oil separator has the following benefits for this system:

[0018] 1. The function of the oil separator is to separate the oil from the hot gas and return the oil to the oil sump of the compressor through its own control device.

[0019] 2. The oil separator can prevent oil shortage and protect the compressor.

[0020] 3. The oil separator can prevent oil from accumulating in troublesome places and reducing efficiency, thus protecting the refrigeration system.

[0021] The pressure switch and the pressure relief valve are used together to provide double protection for the system, preventing overpressure. This is safe and reliable, and the system has a long service life.

[0022] In summary, the heat pump air-conditioning hot water system provided by the utility model has a simple structure, is easy to assemble, has reliable system operation, and has a low failure rate, and can have a broader market prospect. BRIEF DESCRIPTION OF THE DRAWINGS
