Refrigeration system and refrigeration method thereof

Abstract

The invention discloses a refrigeration system which comprises an indoor unit and an outdoor unit, wherein the indoor unit comprises a compressor, a first indoor heat exchanger and a second indoor heat exchanger; the outdoor unit comprises an outdoor heat exchanger; an exhaust port of the compressor is connected with one end of the outdoor heat exchanger; the other end of the outdoor heat exchanger is connected with one end of the first indoor heat exchanger; the other end of the first indoor heat exchanger is connected with a gas returning port of the compressor, so that a loop in an air conditioning mode is formed; the second indoor heat exchanger is lower than the outdoor heat exchanger; one end of the second indoor heat exchanger is connected with one end of the outdoor heat exchanger; and the other end of the outdoor heat exchanger is connected with the other end of the second indoor heat exchanger, so that a loop in a heat tube mode is formed. The invention further discloses a refrigeration method of the refrigeration system. The technical scheme meets cooling requirements at different temperatures of working conditions, the refrigeration efficiency is improved, and the purchase cost of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system and a refrigeration method for the refrigeration system. Background technique [0002] With the development of modern technology, it is necessary to cool down the equipment in the communication base station all year round and around the clock. However, the air conditioners used to cool equipment in the existing base station equipment rooms usually adopt a single air-conditioning cooling mode, that is, a mechanical cooling mode, or a single gravity heat pipe cooling mode; due to seasonal and regional differences, mechanical cooling mode is often used in summer. In other seasons, the gravity heat pipe cooling mode is mostly used. Therefore, in order to meet the cooling requirements of the equipment and obtain a better cooling effect at the same time, usually the base station equipment room will purchase equipment with two cooling modes, so that buyers ...

AI Technical Summary

Problems solved by technology

However, using the air-conditioning cooling mode can obtain enough cooling capacity in the computer room in summer to cool down the equipment, but in other seasons, especially in winter, the advantage of using the air-conditioning cooling mode to cool down is not obvious; and the gravity heat pipe cooling mode has no compressor. Only by changing the state of the refrigerant itself, the cooling capacity is obtained under the premise that there is a certain height difference between the indoor and outdoor units. In this way, due to the influence of the environment and temperature, the cooling capacity of the gravity heat pipe cooling mode is limited.
