Heat exchanger assembly and air conditioner

Abstract

The invention provides a heat exchanger assembly and an air conditioner. The heat exchanger assembly comprises a first heat exchanger (1) and a second heat exchanger (2) which are arranged in parallel, wherein the air inlet ends of the first heat exchanger (1) and the second heat exchanger (2) are connected to an air inlet header pipe (3); the outlet end of the first heat exchanger (1) is connected with a first liquid outlet pipe (4); the outlet end of the second heat exchanger (2) is connected with a second liquid outlet pipe (5); a first flow regulating valve (6) is arranged on the first liquid outlet pipe (4); a second flow regulating valve (7) is arranged on the second liquid outlet pipe (5); the opening degree of the first flow regulating valve (6) is controlled through the outlet refrigerant temperature of the second heat exchanger (2); and the opening degree of the second flow regulating valve (7) is controlled through the outlet refrigerant temperature of the first heat exchanger (1). According to the heat exchanger assembly, it can be effectively guaranteed that the heat exchange capacities of the two heat exchangers connected in parallel are the same, and the heat exchange efficiency of the heat exchanger assembly is improved.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a heat exchanger assembly and an air conditioner. Background technique [0002] In data centers, communication computer rooms and communication base stations, the energy consumption of computer room air conditioners occupies a considerable proportion. The calorific value of various data processing equipment is also increasing, which makes the cooling capacity and heat exchange effect of the air conditioner in the computer room more and more demanding. Therefore, improving the heat exchange effect of the air conditioner in the computer room will become a key research and development of various manufacturers direction. [0003] Most of the existing inter-row computer room air conditioners use a V-shaped design for the condensers, because the liquid outlet pipes of the V-shaped condensers are arranged in multiple ways. During the running of the experiment, it wa...

Problems solved by technology

During this process, the refrigerant liquid in the V-shaped condenser is divided into left and right liquid outlet pipes and converges to the main liquid outlet pipe. Since the direction of outdoor air flowing to the condenser is ever-changing, the heat exchange effect of the left and right sides of the V-shaped condenser is inconsistent. This makes the temperature of the left and right outlet pipes deviate, which further causes the flow of liquid refrigerant in the left and right outlet pipes to be uneven, which also makes the flow of refrigerant in the left and right branch pipes of the V-shaped condenser inconsistent.

Under the influence of various factors, due to the uneven heat transfer effect, the overall heat transfer efficiency of the condenser is affected, and the overall cooling capacity of the unit will be further affected.
