Document Type and Number:
WIPO Patent Application WO/2007/042869
Kind Code:
A1
Abstract:
A hot water device utilizing solar heat and a heat pump is disclosed. The hot water device
comprises a compressor (1), a condenser (2), a throttling device (5) and an evaporating
heat collector (6). An electromagnetic valve (3, 4) is provided in parallel to
the compressor (1) and the throttling device (5) respectively. The gas outlet
of the compressor (1) and the electromagnetic valve (3) are connected to the gas
inlet of the condenser (2) through a pipe. The gas inlet of the compressor (1) and
the electromagnetic valve (3) are connected to the gas outlet of the evaporating heat
collector (6) through a pipe. The liquid outlet of the condenser (2) is connected to
the inlet of the electromagnetic valve (4) and the throttling device (5) through a
pipe. The outlet of the electromagnetic valve (4) and the throttling device (5)
are connected to the liquid inlet of the evaporating heat collector (6) through a
pipe. When the amount of sunshine is sufficient, the hot water device works in the
operating mode of a heat pipe utilizing solar heat. When the amount of sunshine is
insufficient, the hot water device works in the operating mode of a heat pump.
