Title:
COMPLEX CYCLE HEAT PUMP DEVICE
Document Type and Number:
Japanese Patent JP2015083912
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To keep current circumstances that a heat pump device with a principle of reverse Carnot cycle distributed in world-wide basis at present is a prevalent trump card for a future low-carbon society due to its high energy efficiency, a propagation of heat pump device in Japan has been expanded successfully to lead the world and a further improvement in performance of the heat pump under such a circumstance as above has been requested.SOLUTION: In order to solve the aforesaid theme, a present inventor has devised a new heat pump apparatus enabling a substantial improvement in performance to be attained by eliminating a throttle loss at a pressure reducing process carried out by an expansion valve in the present heat pump device under application of a complex cycle by using an expansion machine and activating a driving force of a compressor and refrigerant compressed and heated by the driving force through heat exchanging operation.
