Description

Technical Field

[0001] The utility model relates to the technical field of water circulation equipment, in particular to an air energy hot water system. Background Art

[0002] Large-scale pig farms require hot water for both bathing and domestic use. For a long time, hot water circulation systems in these farms have typically used water heaters, which has resulted in high equipment costs.

[0003] Air-source heat pumps are the primary component of air-source water heating systems. They utilize heat energy from the air to heat water, achieving a thermal efficiency of up to 400%, saving over 75% energy compared to traditional electric water heaters. This indirect heating method significantly reduces energy consumption, meeting modern industrial requirements for energy conservation and emissions reduction while also meeting businesses' need to reduce equipment costs.

[0004] The existing air-to-water heating system is directly put into use in large-scale pig farms. Although it can achieve the supply of hot water, it has the problem that due to the large scale of use, a large number of pipes are required to connect the air-to-water heat pump. When the pipes far away from the air-to-water heat pump are opened for use, cold water flows out first, and it takes a certain amount of time for hot water to flow out, which makes it impossible to achieve instant hot water use. Summary of the Invention

[0005] The utility model aims to provide an air-energy water heating system, which can realize instant use of hot water in pig farms and improve the user experience.

[0006] In order to achieve the above purpose, the utility model provides an air-to-water heating system, the specific implementation scheme is as follows:

[0007] An air-energy water heating system comprises an air heat pump and an insulated water tank, wherein a circulation pipe and a heating pipe are provided between the air heat pump and the insulated water tank;

[0008] One end of the circulation pipe is connected to the air heat energy pump, and the other end is connected to the thermal insulation water tank. A first temperature sensor, a circulation water pump and a plurality of first valves are provided on the circulation pipe. The detection end of the first temperature sensor detects the thermal insulation water tank.

[0009] One end of the heating pipe is connected to the air heat energy pump, and the other end is connected to the thermal insulation water tank, and a second valve is provided on the heating pipe;

[0010] A water supply pipe, a return water pipe and a water supply pipe are connected to the other end of the insulated water tank. The other end of the water supply pipe is connected to an external water supply source, and the other end of the return water pipe is connected to the water supply pipe. The water supply pipe is connected to several water use ends, and a second temperature sensor is provided on the water supply pipe. The detection end of the second temperature sensor detects the water supply pipe.

[0011] In some embodiments, two circulating water pumps are provided in parallel on the circulating pipe, and both of the two circulating water pumps form a loop with the air heat energy pump and the insulated water tank through the circulating pipe.

[0012] In some embodiments, each of the circulating water pumps is connected to a first filter and a first one-way valve.

[0013] In some embodiments, the circulation pipe is connected to a first sewage pipe, and a drain valve is provided on the first sewage pipe.

[0014] In some embodiments, a plurality of water supply valves and second filters are provided on the water supply pipeline, and at least one water supply valve is connected in parallel with the second filter.

[0015] In some embodiments, a first water level sensor, a second water level sensor and a third water level sensor are provided in the insulated water tank, and the first water level sensor, the second water level sensor and the third water level sensor are all electrically connected to the water supply valve.

[0016] In some embodiments, a plurality of return valves and third filters are provided on the return water pipeline, and at least one return valve is connected in parallel with the third filter.

[0017] In some embodiments, the water supply pipeline is provided with two water supply pumps arranged in parallel, the water supply pipeline is provided with a plurality of water supply valves, and each of the water supply pumps is connected to a fourth filter and a second one-way valve.

[0018] In some embodiments, a second sewage pipe is connected to the insulated water tank, the other end of the second sewage pipe is connected to a drain pipe, and a sewage valve is connected to the second sewage pipe.

[0019] In some embodiments, an exhaust pipe is connected to the insulated water tank, and the other end of the exhaust pipe is connected to the outside of the insulated water tank.

[0020] Based on the above technical solution, the air-energy water heating system of the present invention has the following beneficial effects compared with the prior art:

[0021] 1. By setting a return pipe and a water supply pipe on the insulated water tank, the second temperature sensor on the water supply pipe is used to monitor the water temperature in the water supply pipe in real time. When the water temperature is lower than the set temperature, the return pipe is used to transfer the water in the water supply pipe back to the insulated water tank, and the water in the insulated water tank that is greater than or equal to the set stable temperature re-enters the water supply pipe, ensuring that several water-using ends connected to the water supply pipe can use hot water immediately when using water, achieving the effect of hot water being available immediately.

[0022] 2. By setting a circulation pipe between the air heat energy pump and the insulated water tank, the temperature of the insulated water tank is monitored by the first temperature sensor on the circulation pipe. When the temperature of the insulated water tank is lower than the set temperature, the circulating water pump is used to return the water in the insulated water tank through the circulation pipe to the air heat energy pump for heating, and then re-enter the insulated water tank through the heating pipe, thereby ensuring the normal supply of hot water in the hot water system.

[0023] 3. By setting a water supply pipe on the insulated water tank, the water level in the insulated water tank is monitored by using the first water level sensor, the second water level sensor and the third water level sensor in the insulated water tank. When the water level in the insulated water tank is lower than the low water level, the water supply pipe will replenish the water provided by the external water supply source into the insulated water tank, and cooperate with the air heat energy pump, the circulation pipe and the water supply pipe to realize the water flow replenishment and temperature control of the insulated water tank.

[0024] 4. By connecting the second sewage pipe to the insulated water tank and the first sewage pipe to the circulation pipe, scale, impurities and other substances in the insulated water tank can be regularly removed. BRIEF DESCRIPTION OF THE DRAWINGS
