The invention discloses a floor heating and
air conditioning integrated device based on an air source
heat pump technology. The floor heating and
air conditioning integrated device comprises a compressor, a condenser, an
evaporator, expansion valve and other assemblies. In the heating process, the compressor, a four-way valve, the condenser, a single-way valve bridge-type device (A-D), a liquid accumulator, the expansion valve, a single-way valve bridge-type device (B-C), the
evaporator, a gas-liquid separator and the compressor are sequentially connected to form a circulation; in the refrigerating process, the compressor, the four-way valve, the
evaporator, a single-way valve bridge-type device (C-D), the liquid accumulator, the expansion valve, a single-way valve bridge-type device (B-A), the condenser, the gas-liquid separator and the compressor are sequentially connected to form a circulation. The floor heating and
air conditioning integrated device has the advantages of being suitable for installation spaces different in size, simple in structure, low in cost, small in size, convenient to control and the like.
