A dual-collector-distributor four-pipe air-conditioning system coupled with a heat pump unit and a chiller unit and its application method

Abstract

The invention provides a heat pump unit and cold water unit coupled four-pipe air conditioner system with double water collection and distribution devices and a use method of the heat pump unit and cold water unit coupled four-pipe air conditioner system. The heat pump unit and cold water unit coupled four-pipe air conditioner system has the economical, healthy, comfortable, environmental-friendly and energy-saving functions. The manner that a cold water unit is combined with a heat pump unit is adopted for a main machine. A two-pipe water producing system is adopted for the region needing the cold load in summer and only needing the heat load in winter, a four-pipe water producing system is adopted for the region needing the cold load in summer and needing both the cold load and the heat load in winter, and the purposes that cold is supplied in summer, heat is supplied for some region in winter, and cold and heat are supplied to part of the region at the same are achieved. A two-pipe air conditioner system process built by a traditional cold water unit and a heat pump unit is improved, and through the manner that the cold water collection and distribution device and the hot water collection and distribution device are arranged on an air conditioner and the valve switching manner, the heat pump unit and cold water unit coupled four-pipe air conditioner system with the double water collection and distribution devices is built. By means of the heat pump unit and cold water unit coupled four-pipe air conditioner system, the temperatures of all air conditioner regions are controlled precisely, the indoor comfort is improved, and the heat pump unit and cold water unit coupled four-pipe air conditioner system has the beneficial effects of being safe, healthy, comfortable, capable of saving energy and protecting the environment and the like.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system with double collectors and distributors and four pipes with a heat pump unit coupled with a chiller unit and a method for using the same. Background technique [0002] With the development of my country's economy and society and the increase of population density, the scale of new public buildings is getting larger and larger, and the difference between the inner and outer areas of the air conditioner is becoming more and more obvious. The air conditioning system has a cooling load in summer and a heat load in the outer area in winter. , There is a cooling load in the inner area. [0003] The two-pipe air-conditioning system constructed by the traditional commonly used chiller + heat pump unit can only meet a single cooling or heating requirement, and it is difficult to meet the air-conditioning needs of buildings with both cooling and heating loads; The co...

Problems solved by technology

[0003] The two-pipe air-conditioning system constructed by the traditional commonly used chiller + heat pump unit can only meet a single cooling or heating requirement, and it is difficult to meet the air-conditioning needs of buildings with both cooling and heating loads; The controlled air conditioning system can meet the requirements of simultaneous cooling and heating, but the initial investment is large, the operating cost is high, the area of ​​the machine room is large, and there is a possibility of safety accidents in the boiler room
