Abstract

The invention discloses a high-efficiency energy-saving control system of a combined air conditioning unit based on a single cold source. The high-efficiency energy-saving control system of the combined air conditioning unit based on the single cold source comprises an equipment part, and a pipeline and valve part for connecting various equipment, wherein the equipment part comprises a refrigeration host, a fan coil for cooling, and a fresh air unit for dehumidifying; and the pipeline and valve part comprises a coiler check valve, a coiler adjusting valve, a secondary adjusting valve, a freshair check valve, a fresh air water-return valve, a fresh air adjusting valve, a water return adjusting valve, a bypass valve, and pipelines for connecting the various equipment and the valves. According to the scheme, the refrigeration host has no need to produce two chilled water. Through valve adjustment, the chilled water supply amount of a dehumidifying system and a cooling system can be reasonably distributed. The aim of meeting different demands on the temperature of the chilled water required for cooling and dehumidifying under the condition of a single cold source is achieved.

Description

technical field [0001] The invention belongs to the field of air-conditioning technical equipment, and in particular relates to a high-efficiency and energy-saving control system for a combined air-conditioning unit based on a single cold source. Background technique [0002] In a conventional central air-conditioning system, in order to improve the operating efficiency of the system, medium-temperature chilled water is often used for cooling, and low-temperature chilled water is required when there is a need for dehumidification. The load used for dehumidification generally only accounts for 20-30% of the total load. In order to meet the overall use requirements of the air conditioner, the user has to use the low-temperature water mode for the host with a single cold source, or use two sets of air conditioning systems, or use a special one. The main engine or air conditioning unit, in this way, the system efficiency is low, the system complexity increases, and the cost is t...
