Evaporative condensation device

Abstract

The invention discloses an evaporative condensation device, which comprises an evaporation compressor set and an evaporative condenser, wherein the evaporation compressor set comprises a heat exchanger and a compressor; the heat exchanger is used for performing heat exchange between chilled water and refrigerants, so that the refrigerants are vaporized through heat absorption; the compressor is used for pressurization liquidation of the vaporized refrigerants; the evaporative condenser comprises an upper layer heat exchange region, a lower layer heat exchange region and a cooling water treatment system; the upper layer heat exchange region is used for precooling the refrigerants liquefied by the compressor through air; the lower layer heat exchange region is used for cooling the precooled refrigerants through cooling water and introducing the cooled refrigerants into the heat exchanger; the cooling water treatment system comprises a chemical adding device which is used for feeding chemicals into circulation cooling water for controlling the dirt of the circulation cooling water. A monitoring device is used for monitoring the water quality in real time, and controlling the dosing quantity of the dosing device according to the water quality information, so that the water quality change is controlled in real time.

Description

technical field [0001] The invention relates to a condensation device, in particular to an evaporation condensation device applied to a subway station. Background technique [0002] With the rapid development of the subway project and the increasing shortage of urban land, it is difficult to acquire land for the subway, and the cost of demolition is extremely high. As the ground ancillary facilities of the subway underground station, the ground cooling tower has a negative impact on the urban landscape and environment. The cooling tower is subject to many restrictions such as landscape, environmental noise, and land acquisition, and even the ground cannot be placed. In order to solve this problem, some stations cancel the ground cooling tower and adopt evaporative condensing air conditioning system. [0003] The evaporative condensing unit is a new technology cold source equipment that has just been applied exploratoryly in subway stations in recent years. The evaporative ...
