Abstract

The invention belongs to the field of technical equipment of air conditioners and in particular discloses a balanced energy-saving control device based on a secondary pump system of a central air-conditioner. The device comprises a main machine, a general water collector, a general water separator and an axle tube. The input end of the main machine is connected to the general water collector, theoutput end of the main machine is connected to the general water segregator, and a primary pump is arranged between the main machine and the general water collector; the secondary pump is arranged atthe output end of the general water segregator, and the axle tube is connected between the output end of the general water collector and the input end of the general segregator; an energy-saving control unit is arranged on the axle tube, and a bypass pipe is arranged at each of two ends of the energy-saving control unit; and a bypass valve is additionally mounted on the bypass pipe. According to the scheme, an existing air conditioner system is improved. By additionally mounting the energy-saving control unit of the secondary pump system, the time of a refrigerating main machine in a low efficiency working condition is shortened and the efficiency of the refrigerating main machine is improved while meeting the demand on cooling capacity.

Description

technical field [0001] The invention belongs to the field of air-conditioning technical equipment, and in particular relates to a balance energy-saving control device based on a central air-conditioning secondary pump system. Background technique [0002] The efficiency of the air conditioner will decrease when the load is too high and too low. However, in the past central air-conditioning control systems, if one host is used, the load on the host is high and the efficiency is low; if two hosts are used, the loads of both hosts are very low, and the efficiency of the host is still low. In the actual use of an air conditioning system with a secondary pump system, the water pump of the secondary system often has a larger flow rate than the water pump of the primary system, often forming a mixed temperature phenomenon where the chilled return water flows through the bridge pipe to the chilled supply water. The temperature mixing phenomenon increases the temperature of chilled ...
