An integrated dual-source refrigeration station and refrigeration method

Abstract

The invention discloses an integrated double-source freezing station and a refrigerating method. The integrated double-source freezing station comprises a water cooling unit (1), an intermediate heat exchanger (10), a cooling water system, a freezing water system and a control system, wherein the water cooling unit is arranged between the cooling water system and the freezing water system; the intermediate heat exchanger and the water cooling unit share water supplying and returning pipelines of the cooling water system and the freezing water system; the water cooling unit, the intermediate heat exchanger, the cooling water system, the freezing water system and a three-way valve are controlled by the control system; the cooling water system comprises a cooling tower (3), and a cooling water pump (2) which is arranged on a water outlet pipeline of the cooling tower; the freezing water system comprises a freezing water pump (11), a constant-pressure expansion tank (13) and an incrustation cleaner (13) which are sequentially arranged on a water supplying pipeline of the freezing water system along the water supplying direction. The integrated double-source freezing station and the refrigerating method are easy to implement, and obvious in energy saving effect.

Description

technical field [0001] The invention relates to an integrated dual-source freezing station and a refrigeration method. Background technique [0002] With the rapid development of China's communication industry and the continuous expansion of communication network scale, the electricity cost of communication enterprises is also rising continuously. In 2015, under the overall recovery of the macroeconomic situation and the continuous expansion of information and communication demand, with the full implementation of industrial policies such as information consumption, broadband strategy, and 4G, the information and communication industry is expected to continue to maintain a stable and rapid development trend. It is expected that the overall The growth rate will still exceed 10%, of which the basic telecommunications industry will grow by about 8%, and the value-added Internet sector will grow by more than 30%. The overall market revenue will exceed 1.6 trillion yuan. In order...

Problems solved by technology

Although the direct introduction of fresh air energy-saving system is simple in structure and small in size, it requires frequent replacement of filters, which is expensive and cannot guarantee the humidity requirements in the machine room; Therefore, the volume is large, and it is mainly used in the computer room with a large space; and the two methods are supplementary products of the original air conditioner in the computer room, and need the cooperation of the traditional refrigeration air conditioner to operate

[0004] It can be seen from the above scheme that the use of natural cold source can reduce the energy consumption of the air conditioning system in the communication room, but it needs the cooperation of the original air conditioner and cannot completely replace the original air conditioner
