Energy-saving air conditioner using outdoor cold source indirectly

Abstract

The invention discloses an energy-saving air conditioner using outdoor cold source indirectly, which is suitable for occasions having great heating quantity and needing refrigeration in winter, such as communication machine rooms and computer rooms. The energy-saving air conditioner consists of indoor machine subassemblies, and an air-cooled condenser, a liquid reservoir, a fluorine pump and a capillary tube which are positioned outside the room, wherein the indoor machine subassemblies comprise a compressor, an evaporator and the like and are connected with an inlet of the air-cooled condenser through a connecting pipeline; the liquid reservoir is installed on a connecting pipeline between an outlet of the air-cooled condenser and the indoor machine; and the fluorine pump is connected with another branch at the outlet of the liquid reservoir, thus forming a separate refrigerating circulation system with the air-cooled condenser, the evaporator and the capillary tube. The air conditioner lowers the temperature by a refrigerating system in summer. When the outdoor temperature is lower than a certain pre-set temperature, the fluorine pump energy-saving system operates. A fluorine pump refrigerating circulation system is added, and outdoor cold source can be utilized at appropriate outdoor ambient temperature without opening the compressor, thus reducing the running energy consumption of the air conditioner, shortening the working time of the compressor and prolonging the service life of the compressor.

Description

technical field [0001] The invention relates to an air-cooled air conditioner, in particular to an energy-saving air conditioner capable of indirectly using an outdoor cold source for an air conditioner in a machine room at a suitable outdoor ambient temperature. Background technique [0002] Energy is an important material basis for the survival and development of human society. Throughout the history of the development of human society, every major progress of human civilization is accompanied by the improvement and replacement of energy. The development and utilization of energy has greatly promoted the development of the world economy and human society. At present, energy shortage has become a problem to be solved by the whole society, and energy conservation and emission reduction has become a basic national policy of our country. In recent years, the communication industry has developed rapidly and has become a high-tech industry, as well as an industry that consumes...
