Water supply improvement device used for small ground source heat pump

Abstract

The invention discloses a water supply improvement device used for a small ground source heat pump. Both ends of a water inlet pipe are connected to a heat pump unit. One end of a water outlet pipe isdefinitely connected to the heat pump unit, and the other end of the water outlet pipe is arranged in a water storage tank. A filter screen is arranged on the portion, located in the water storage tank, of the water outlet pipe. A water delivery pipeline is fixedly connected to the water storage tank. A temperature sensor and a purification device are arranged on the water delivery pipeline, anda first water pump and a first control valve are also arranged on the water delivery pipeline. The water delivery pipeline is connected with a first pipeline and a second pipeline through a three-wayquick connector. A second control valve is arranged on the first pipeline, and the other end of the first pipeline is arranged on a water tank. A third control valve is arranged on the second pipeline, and the other end of the second pipeline is connected to a heating water storage tank. A third pipeline is connected to the heating water storage tank, and the other end of the third pipeline is arranged on the water tank. A second water pump is further arranged on the third pipeline.

Description

technical field [0001] The invention relates to the technical field of a water supply system, in particular to a water supply improvement device for a small ground source heat pump. Background technique [0002] With the development of the economy and the improvement of people's living standards, heating, hot water, and air conditioning in public buildings and residences have become common requirements. As China's traditional heating, coal-fired boilers not only have low energy efficiency, but also cause air pollution. Serious pollution, so coal-fired boilers are being phased out in some cities, while oil-fired and gas-fired boilers have high operating costs. Using ground source heat pumps is a good alternative. In the use of existing ground source heat pumps The waste heat recovery of some ground source heat pumps is less than the cooling capacity. For projects with a large domestic hot water demand, the waste heat recovery matched according to the cooling load of the air c...

[0002] With the development of the economy and the improvement of people's living standards, heating, hot water, and air conditioning in public buildings and residences have become common requirements. As China's traditional heating, coal-fired boilers not only have low energy efficiency, but also cause air pollution. Serious pollution, so coal-fired boilers are being phased out in some cities, while oil-fired and gas-fired boilers have high operating costs. Using ground source heat pumps is a good alternative. In the use of existing ground source heat pumps The waste heat recovery of some ground source heat pumps is less than the cooling capacity. For projects with a large demand for domestic hot water, the waste heat recovery matched according to the cooling load of the air conditioner cannot meet the domestic hot water consumption, and it is wasteful to configure a separate boiler to heat domestic hot water. In addition to the function of waste heat recovery of ground source heat pump, the temperature of domestic hot water heated by ground source heat pump is 45-55 ℃, and some projects require domestic hot water to be above 60 ℃. Therefore, it is necessary to design a small ground source heat pump water supply improvement device, so that the hot water provided by the ground source heat pump can meet the user's requirements, and make the ground source heat pump more practical
