Title:

HYBRID-DRIVEN COLD/HEAT STORAGE TYPE HEAT PUMP UNIT UTILIZING SOLAR PHOTOVOLTAIC POWER AND COMMERCIAL POWER

Document Type and Number:

WIPO Patent Application WO/2010/081421

Kind Code:

A1

Abstract:

A hybrid-driven cold/heat storage type heat pump unit utilizing a solar photovoltaic power and a commercial power, which has a DC compressor (2) and an AC compressor (8), is a dual supply heat pump system driven by a solar photovoltaic DC power and a common commercial AC power in combination. When there is sunshine, the DC generated by a solar cell panel (60) is used for driving the DC compressor (2) directly to produce cold and heat capacity, and the produced cold and heat capacity could be stored respectively in a phase-change cold storage medium (39) and a phase-change heat storage medium (20). When the DC power is insufficient, the AC power from power network is used for power supply.
