Description

Technical Field

[0001] The utility model relates to the field of machinery, specifically to water source heat pump technology, and more specifically to a cleaning unit. Background Art

[0002] Since the circulating water in the water source side circulating water system is taken from a well, there are problems such as corrosion, scaling, bacteria and algae, and water quality deterioration when the groundwater accumulates or flows inside the equipment. If the circulating water is not cleaned, the long-term use of these well waters will reduce the service life of the unit and the terminal equipment, and further cause failures in the water source heat pump system. In the light case, it will reduce the heat exchange efficiency, increase power consumption, and cause energy waste. In the heavy case, it will corrode the copper pipe and cause the groundwater to backfill into the refrigeration system, ultimately resulting in serious consequences such as compressor scrapping.

As shown in the figure, the water outlet end 101 on the water source side of the water source heat pump unit 100 is connected to the system water inlet 202 of the fully automatic system water cleaning unit 200. The system water inlet 202 is connected to the hydrocyclone 6 through the first electric valve 1; the outlet of the hydrocyclone is connected to the inlet of the chemical dosing tank 9.

The system water outlet 201 is connected to the water inlet end 102 on the water source side; the system water make - up port 203 is connected to the chemical dosing tank 9 through the third electric valve 3; the system water make - up port 203 is connected to the hydrocyclone 6 through the second electric valve 2; the water flowing out of the purified water outlet of the water purification sand filter is the tertiary purified water D; a pH value transmitter 11 and a pressure transmitter 12 are provided on the connecting pipeline between the purified water outlet of the water purification sand filter and the inlet of the chemical industry circulation pump 8; the sewage outlet of the water purification sand filter is connected to the system sewage outlet 204 through the fifth electric valve 5.

[0011] To achieve automatic control, the first to fifth electric valves, pressure transmitter, pH value transmitter, and chemical industry circulation pump are all connected to the control center. The control center is a PLC.

[0012] The underflow outlet of the hydrocyclone 6 is connected to the fifth electric valve 5.

[0013] The circulating water cleaning principle of the present utility model:

[0014] The circulating water on the water source side in the water source heat pump unit equipment flows into the water inlet 202 of the fully automatic water cleaning unit through the water outlet end on the water source side of the unit. The first electric valve 1 controls the switch of the inflow of the circulating water.

[0015] The internal circulating water of the system flows into the hydrocyclone 6 through the first electric valve 1. By making the circulating water flow along the inner wall of the hydrocyclone, a swirl is generated, causing large particles such as sand grains and water channels in the circulating water to settle to the bottom of the hydrocyclone along with the swirl. Subsequently, the primary purified water B flows from the top outlet to the chemical dosing tank 9.

[0016] The switch of the third electric valve 3 is controlled by the pH value transmitter 11 to control the flow of tap water from the system water make - up port 203 to the chemical dosing tank. The primary purified water B becomes the secondary purified water C through the chemical dosing tank and flows to the water purification sand filter 7.

[0017] The secondary purified water C flows into the purified water sand filter 7, and harmful substances such as organic matters, peculiar smells, colors, and small particles in the water are adsorbed by filter materials such as quartz sand, activated carbon, and manganese sand in the sand filter, providing high-quality tertiary purified water D to the equipment;

[0018] The tertiary purified water D flows back to the water inlet end 102 of the water source side of the water source heat pump unit through the control of the chemical circulation pump 8 and the fourth electric valve 4, completing the cleaning process of the circulating water.

[0019] The water replenishment principle in the equipment and system of the present utility model:

[0020] ① The water replenishment principle of the circulating water:

[0021] 1. If the water volume stored in the equipment fails to reach the starting water volume, or the water volume inside the water source heat pump unit decreases due to operation and the heat exchange efficiency is reduced, the water flow can be controlled through the pressure transmitter 12 via the second electric valve 2 at the system water replenishment port 203;

[0022] ② The water replenishment in the water source heat pump system:

[0023] The water is made to flow into the equipment through the system water replenishment end by the control center;

[0024] The water at the water replenishment end is made to flow into the water source heat pump equipment through the circulating pump to achieve the function of water replenishment in the system

[0025] The internal circulation cleaning principle of the equipment of the present utility model:

[0026] Water enters from the system water replenishment port, flows into the hydrocyclone 6 and the purified water sand filter 7 through the second electric valve 2, and after being aggregated, flows out of the fully automatic water cleaning unit through the fifth electric valve 5, becoming the sewage to be treated and flowing into the sewage treatment device.
