Abstract: |
This invention discloses an electric heat pump heat collection device with gas/oil boiler smoke potential heat including a boiler, heat exchanger, heat supply tube and an electric heat pump composed of a compressor, a cooler, an expansion valve, evaporator and connection tubes; part of the said heat supply tube is set through the cooler. The invention combines the electric heat pump with gas/oil boiler to utilize the potential heat of vapor in the boiler smoke to meet the needs of low temperature heat resources by electric heat pump and increase the efficiency of gas, oil boiler. |
