Air conditioning system combining multi-split air conditioner and cold and hot water unit and control method thereof

Abstract

The invention relates to an air conditioning system combining a multi-split air conditioner and a cold and hot water unit and a control method of the air conditioning system. The multi-split air conditioner comprises an outdoor unit and a plurality of indoor units; a water fluorine heat exchanger is arranged in the cold and hot water unit; a liquid pipe of each indoor unit and a liquid pipe of thewater fluorine heat exchanger are gathered and then are connected to a liquid pipe stop valve of the outdoor unit; an air pipe of each indoor unit and an air pipe of the water fluorine heat exchangerare gathered and then are connected to an air pipe stop valve of the outdoor unit; a first electronic expansion valve is arranged at the liquid pipe end of each indoor unit; and a second electronic expansion valve is arranged at the liquid pipe end of the water fluorine heat exchanger. According to the air conditioning system combining the multi-split air conditioner and the cold and hot water unit and the control method of the air conditioning system, the rotating speed of a compressor and the electronic expansion valves of the multi-split air conditioner and the cold and hot water unit canbe adjusted by detecting the temperatures of the liquid pipes and the air pipes, the outlet water temperature and the return water temperature, the two units operate at the same time, respective characteristics are brought into play, and the requirements of users are fully met.

Description

technical field [0001] The present invention relates to an air conditioner and its control method, in particular to a combined air conditioner and its control method, in particular to an air conditioner system combined with multiple units and cold and hot water units and its control method. Background technique [0002] Multi-connected and air-cooled module cold and hot water units are two common air-conditioning systems at present. Their basic principles are the same, and most of the components of the products are the same. This kind of product causes waste of resources to a certain extent. [0003] At present, although there are also products that combine these two types of units, the multi-connection and hot and cold water units cannot be used at the same time, which is difficult to meet the needs of users. [0004] Therefore, it needs to be improved so that it can better meet the needs of the market. Contents of the invention [0005] The purpose of the present inven...
