Circulating cooling water system

Abstract

The invention discloses a circulating cooling water system which comprises a cooling water tower, a refrigerating unit, a three-way valve and a heat exchanger. A water outlet of the cooling water tower, a condenser water inlet of the refrigerating unit and a water inlet of the heat exchanger are connected together through the three-way valve. An evaporator water outlet and an evaporator water inlet of the refrigerating unit are connected with the water inlet and a water outlet of the heat exchanger respectively. Working in the two modes can be achieved by controlling the communication relation of the three-way valve. According to different external environmental conditions, the different working modes can be selected to operate the system, so that the energy consumption is lowered, the refrigerating unit is switched off and only the cooling water tower is switched on particularly on the condition that the external environment temperature is low, the electricity consumption cost can be remarkably lowered, and the effect of energy conservation is achieved.

Description

technical field [0001] The invention relates to the field of cooling equipment, in particular to a circulating cooling water system. Background technique [0002] In modern industrial production and manufacturing, such as semiconductor components, optical fiber equipment, hood equipment, glass factory equipment and other industrial products, as well as large-scale scientific research laboratories, many places need circulating cooling water systems to provide process water with constant temperature for absorption production or experiments Heat dissipation of the device. [0003] However, the traditional large-scale circulating cooling water system simply relies on the refrigeration unit as a single cooling device, which has a large power and is the main energy-consuming device of the system. In actual operation, the circulating cooling water system is basically at full load. When the system runs for many years, the power consumption is large and the operating cost is high. I...

[0003] However, the traditional large-scale circulating cooling water system simply relies on the refrigeration unit as a single cooling device, which has a large power and is the main energy-consuming device of the system.

In actual operation, the circulating cooling water system is basically at full load. When the system runs for a long time, the power consumption is large and the operating cost is high. It is necessary to take certain measures to reduce the long-term operating cost
