Refrigerating equipment and valve control method thereof

Abstract

The invention discloses refrigerating equipment and a valve control method thereof. The refrigerating equipment comprises an evaporator and a heat exchanger, wherein a water inlet of the evaporator is connected with that of the heat exchanger through a pipeline; an evaporator inlet valve, a water return switching control valve and a heat exchanger inlet valve are arranged on the pipeline from the water inlet of the evaporator and the water inlet of the heat exchanger in sequence; a water outlet of the evaporator is connected with that of the heat exchanger through the pipeline; an evaporator outlet valve, a water supply switching control valve and a heat exchanger outlet valve are arranged on the pipeline from the water outlet of the evaporator and the water outlet of the heat exchanger in sequence; and a cross pipeline is led out from the pipeline between the evaporator inlet valve and the water return switching control valve and is connected to the pipeline between the water supply switching control valve and the heat exchanger outlet valve. The refrigerating equipment is formed in such a way that the heat exchanger is additionally arranged in a water-cooled chiller and the general evaporator, the heat exchanger, the pipelines, the valves and others are connected; and the evaporator and the heat exchanger are controlled, so that the cooling temperature difference of the evaporator is reduced, the working energy consumption of the refrigerating compressor is effectively reduced, and the electric resource is greatly saved.

Description

technical field [0001] The invention belongs to the field of air-conditioning and refrigeration, and relates to an air-conditioning refrigeration device, in particular to a refrigeration equipment and a valve control method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, various industries such as finance, network, communication, and electric power have experienced a trend of large data concentration. The construction of large-scale data room has made various industries put forward high requirements for the concealment, safety and reliability of the data room. At the same time, the huge energy consumption loss of the air conditioning and refrigeration system of the data room has also added a lot of burden to various industries. [0003] In order to meet the needs of social development and the national energy-saving policy, there are a wide variety of energy-saving products and various energy-saving meas...

Problems solved by technology

The construction of large-scale data computer rooms has made various industries put forward high requirements for the concealment, safety and reliability of data computer rooms. At the same time, the huge energy consumption loss of air conditioning and refrigeration systems in data computer rooms has also added a lot of burden to various industries.

[0003] In order to meet the needs of social development and the national energy-saving policy, there are a wide variety of energy-saving products and various energy-saving measures, but the refrigeration system and refrigeration form are single. These technologies or products often increase the initial investment of the project a lot, but the energy-saving effect is not ideal.
