Operation control method of heating and fresh air integrated treatment air-conditioning unit

Abstract

The invention discloses an operation control method of a heating and fresh air integrated treatment air-conditioning unit. Operation modes comprise a cold supply and dehumidification mode, a cold supply mode, a dehumidification mode, a heat supply mode, a heat supply and humidification mode and the like. The invention discloses the control method corresponding to all the operation modes. By regulating variable load operation of all loops in an air-conditioning system, heat and humidity control can be achieved. According to the control method, operation of the multiple modes of the air-conditioning unit can be controlled, the method can adapt to operation of whole-year variable working conditions, during operation, measures of pre-dehumidification and pre-humidification are adopted, harm caused by moisture condensation of the tail end of radiation is effectively avoided, the purpose of controlling temperature and humidity is achieved through variable load operation, the control method is intelligent and simple, cold and heat mixing is reduced in solution variable load operation, meanwhile, a concentrated solution is stored for energy storage, and the method has the advantages of high energy efficiency and low energy consumption.

Description

technical field [0001] The invention relates to a control method, in particular to an operation control method for an air conditioning unit that integrates cooling, heating and fresh air. Background technique [0002] With the rise of living standards, people's requirements for thermal comfort in the residential building environment are also increasing. As a new type of air conditioning terminal, the radiant cooling / heating system has the advantages of low energy consumption, high thermal comfort, low noise, Significant advantages such as saving building space have received widespread attention. Under refrigeration conditions, due to the low surface temperature of the radiant cooling end and the high relative humidity in the room, condensation will occur on the surface of the radiant end. The condensation will cause mildew, hair growth, rust, and corrosion on the object At this time, efficient indoor dehumidification means are the technical key to avoid condensation at the ...
