Combined type double-cold-source refrigerating system

Abstract

The invention discloses a combined type double-cold-source refrigerating system which comprises a cold source unit, a condensation unit, and a draught fan unit, wherein the cold source unit comprises a lower shell provided with an accommodating cavity, as well as a Freon cold source, a compressor, an evaporator and an expansion valve which are arranged in the lower shell and are sequentially connected through a first pipeline, and a glycol cold source connected with a second pipeline; the condensation unit is used for refrigeration and comprises a middle shell; the middle shell is matched with the lower shell, is arranged above the lower shell, and is provided with an accommodating space; a water collecting disc is further arranged between the condensation unit and the cold source unit; the draught fan unit is used for induced draft and air supply; the cold source unit, the condensation unit, and the draught fan unit are sequentially assembled from the bottom up to form an integrated structure; hot air flow enters the combined type double-cold-source refrigerating system from an air inlet in one side of the lower shell, exchanges heat via the condensation unit from the bottom up through the draught fan unit to form cold air flow, and is blown off from the upper part of an upper shell.

Description

technical field [0001] The invention relates to a refrigeration device. More specifically, the present invention relates to a combined dual cold source refrigeration system. Background technique [0002] In today's society, the severe energy shortage situation has attracted widespread attention from the whole society, and the introduction of energy-saving and emission-reduction measures cannot wait. In recent years, the communication industry has developed rapidly and has become a large energy consumer. The annual total power consumption of several major communication operators has reached more than 20 billion kWh. Among them, the power consumption of communication switching equipment and special air conditioners in computer rooms accounts for about 90%. With the development of the communication industry, the number of mobile communication base stations is still increasing, and the total power consumption of base station equipment rooms is increasing. Reducing the power co...
