Coordinated-control synchronous-multi-cycle heat-pump heating-cooling air conditioner composite system

Abstract

The invention belongs to the technical field of heating ventilation air conditioners and relates to a coordinated-control synchronous-multi-cycle heat-pump heating-cooling air conditioner composite system. The system has the beneficial effects that a cooling and heating scope of a traditional air conditioning unit is broadened through design of a multi-cycle access, and cooling and heating capacities of a heat-pump heating-cooling air conditioner are enhanced comprehensively, so that an efficient ultralow-temperature heating cycle and an efficient ultrahigh-temperature cooling cycle are realized; prominent problems that an existing heat-pump heating-cooling air conditioner is high in energy consumption, small in environment-adapted temperature scope and small in application scope are solved effectively; and unification of efficient energy saving and reliable running of the system is realized.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a coordinated control and synchronous multi-cycle heat pump type heating and air conditioning composite system. Background technique [0002] The cooling and heating upper limit effect of the traditional air conditioning system is limited. At low ambient temperature (about -10~-15°C), the heat pump heating and cooling air conditioner turns on the normal heating mode and cannot perform normal heating. At high ambient temperature (about 43°C) Under normal conditions, the heat pump heating and cooling air conditioner turns on the normal cooling mode and cannot cool normally. Contents of the invention [0003] The present invention overcomes the problem of small cooling and heating ranges of traditional air-conditioning units, and realizes comprehensively improving the cooling and heating capabilities of the heat pump heating and cooling air-conditioning system. Aiming at the above pr...
