Problems solved by technology

[0002] In the central air-conditioning water system, the exhaust must be ventilated when the system is running. The common method is to install an automatic exhaust valve at the highest point of the water system to exhaust the air. Since the system is a closed cycle, the indoor air disc and the main unit are connected to a complex waterway, and the pipeline The high-speed moving water vapor in the medium is not easy to discharge, which often leads to poor heat exchange of the central air-conditioning system and high and low pressure faults, causing cavitation of the water pump

Abstract

The invention discloses a central air-conditioning water system. The central air-conditioning water system comprises a central air-conditioning refrigeration unit, a flow switch, a user load, a filter, a water pump, a check valve, a pressure meter and a thermometer which are in circulating connection in sequence through a pipeline, wherein a transition water tank is connected with the pipeline between the filter and the water pump; a water inlet which is connected with the filter is formed in one side of the upper part of the transition water tank; a water outlet which is connected with the water pump is formed in the other side of the lower part of the transition water tank; an exhaust hole is formed in the top of the transition water tank. According to the invention, the transition water tank is additionally arranged, so that no air bubble exists at the inlet of the water pump; the system air can be quickly emptied; the pressure of return water of the system is zero; the system water flow is increased; the system can reliably work; the heat exchange efficiency is increased; the water replenishing, sewage disposal and cleaning of the system are convenient.

Description

technical field [0001] The invention relates to the field of water-cooled central air conditioners, in particular to a central air conditioner water system. Background technique [0002] In the central air-conditioning water system, the exhaust must be ventilated when the system is running. The common method is to install an automatic exhaust valve at the highest point of the water system to exhaust the air. Since the system is a closed cycle, the indoor air disc and the main unit are connected to a complex waterway, and the pipeline The high-speed moving water vapor in the air is not easy to discharge, which often causes poor heat exchange of the central air-conditioning system and high and low pressure faults, causing cavitation of the water pump. Contents of the invention [0003] The purpose of the present invention is to provide a central air-conditioning water system to improve the exhaust problem of the existing airtight central air-conditioning water system, increa...
