Embodiment Construction

[0013] Referring to the accompanying drawings, the present invention includes a water heat exchanger 1, a circulating water pump 4, a stuffing tank 5 equipped with a descaling agent, a drain valve 3, a three-way valve and an electromagnetic valve. The water inlet pipeline and the water outlet pipeline of the water heat exchanger 1 are respectively connected with three-way valve one 8 and three-way valve two 9 . The bypass of the three-way valve one 8 is connected to the bypass of the three-way valve two 9 through the solenoid valve one 2, the circulating water pump 4, the stuffing tank 5 and the solenoid valve two 6 successively. A drain valve 3 is connected on the pipeline between the solenoid valve one 2 and the circulating water pump 4 .

[0014] Before the device of the present invention works, the operation of the central air-conditioning system is stopped. The solenoid valve one 2 and solenoid valve two 6 are opened by the control system, and the circulating water pump ...

Abstract

This invention is descaling device for air conditioner heat pump assembly water heat exchanger. It includes water heat exchanger, circulating water pump, filling tank with scale dissolver, drain valve, three-way valve and magnet valve. The water inlet pipeline and water outlet pipeline of the said water heat exchanger are connected to three-way valve one and three-way valve two respectively. The bypass of the three-way valve one connects to the bypass of the three-way valve two through magnet valve one, circulating water pump, filling tank and magnet valve two. The pipeline between magnet valve one and circulating water pump is connected with drain valve. This invention can automatically remove the scale in the water heat exchanger under the operation of controlling system. Its descaling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a descaling device for water heat exchangers in air-conditioning heat pump units. Background technique [0002] After the water heat exchanger in the central air-conditioning heat pump unit works for a period of time, scale will adhere to the surface of the water heat exchanger. If the scale is not removed in time, it will cause a lot of harm to the unit: Compared with the thermal conductivity of the heat exchanger material, the thermal conductivity of the scale is much smaller, so the heat transfer resistance of the heat exchanger is increased and the heat transfer resistance of the heat exchanger is reduced. The heat exchange reduces the cooling and heating capacity of the whole unit; the generation of scale will lead to the deterioration of the condensing pressure and evaporation pressure, and increase the power consumption of the compressor; the scale will re...
