Evaporative condenser system having self-cleaning function and control method

Abstract

The invention discloses an evaporative condenser system having a self-cleaning function and a control method. The system comprises a heat exchanger as well as a water storage box, a spraying water pump and an atomizing spraying branch which are connected in series through pipelines; the atomizing spraying branch directly faces the heat exchanger and can spray water mist; the atomizing spraying branch is connected with a cleaning spraying branch in parallel; the cleaning spraying branch comprises a connecting pipe I, multiple cleaning nozzles and a solenoid valve I; the cleaning nozzles and thesolenoid valve I are mounted on the connecting pipe I; and two ends of the connecting pipe I are connected with the pipelines. The method includes control on the atomizing spraying mode and the self-cleaning mode. By the aid of the system and the method, scale condensation and dust attachment can be avoided effectively, normal working of a condenser can be guaranteed, and meanwhile, the purposesof avoiding scaling and dust adhesion are achieved with the control method.

Description

technical field [0001] The invention relates to a condensing system, in particular to an evaporative condenser system with automatic cleaning function and a control method for the system. Background technique [0002] In high temperature weather, the heat transfer effect of the outdoor condenser becomes poor, the condensing temperature rises, and the energy consumption of the cooling system in the machine room increases. In addition, the air-cooled condenser is prone to high-pressure alarms, which affect the safe operation of the machine room. The evaporative condenser adopts a spray system to The cooling water is atomized into small droplets through the nozzle and sprayed on the condenser, and the heat of the refrigerant in the condenser is absorbed by the evaporation of the droplets. Due to the small volume of the atomized droplets, the heat exchange with the high-temperature refrigerant can quickly evaporate, and its exchange The thermal efficiency is very high, and the c...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that in the prior art, when the evaporative condenser is in operation, the sundries in the water are easy to scale on the surface of the heat exchanger, and when the operation is stopped, the dust is easy to agglomerate and adhere to the heat exchanger under the action of water mist. The surface of the condenser causes low heat exchange efficiency and affects the effect of spray evaporation. An evaporative condenser system with self-cleaning function is provided. This system can effectively avoid the condensation of scale and the adhesion of dust, and can ensure the normal operation of the condenser. At the same time, the purpose of avoiding fouling and dust adhesion is achieved through this control method
