Putting heat exchanger to be produced by solution-air heat exchange, in external heat exchanger, the medium with air heat-exchange is anti-icing fluid.
Heating-refrigeration hybrid system that mono-/bis-level the most according to claim 3 is run, it is characterised in that: described
Mono-/bis-level run heating-refrigeration hybrid system can be heating twin-stage operational mode, heating single-stage operational mode and
Refrigeration mode:
When the heating-refrigeration hybrid system of mono-/bis-level is in heating twin-stage operational mode, air source heat pump and double heat
Source heat pump series connection, double heat source heat pump is water resource heat pump mode of operation, the heat supply that the heat of thermal source is produced by air source heat pump,
Buffer tank, now buffer tank water outlet circulating pump, energy supply water outlet of water tank and double thermal source heat are connected between two heat pumps
Circulating pump between pump condenser water inlet is standby or running status；
When heating-refrigeration hybrid system that described mono-/bis-level is run is in heating single-stage operational mode, air source heat
Pump is used in parallel with double heat source heat pump, and end system is heated for thermal source by double heat source heat pump with air, by external heat exchange
Device absorbs the heat in air, circulating pump between external heat exchanger and double heat source heat pump vaporizer, energy supply water outlet of water tank with
The circulation between circulating pump, energy supply water outlet of water tank and air source heat pump water inlet between double heat source heat pump condenser water inlet
Pump is standby or running status；
When described mono-/bis-level run heating-refrigeration hybrid system be in cooling operation mode time, double heat source heat pump with
Air source heat pump is refrigeration mode and for state used in parallel, double heat source heat pump with air for low-temperature receiver to end system system
Cold, now circulating pump, energy supply water outlet of water tank between external heat exchanger and double heat source heat pump vaporizer are cold with double heat source heat pump
The circulating pump between circulating pump, energy supply water outlet of water tank and air source heat pump water inlet between condenser water inlet be standby or
Running status.
