Cooling and heating capacity, so as to realize high-efficiency ultra-low temperature heating cycle and ultra-high temperature refrigeration cycle, effectively solve the existing heat pump type cooling and heating air conditioner, such as large energy consumption, small adaptable ambient temperature range and application range, etc., and realize high efficiency and energy saving of the system Unity with reliable operation.

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...
