潜熱蓄熱装置を具備した圧縮式ヒ−トポンプ

<P>PROBLEM TO BE SOLVED: To reduce a load related to a compression type heat pump, to improve COP, and to add convenience in use in a cold district by using a latent heat storage device applying properties inherent to latent heat storage raw material as a means for miniaturizing a compression type heat pump apparatus, and using characteristics of superiority of potential heat capacity per unit or of carrying out heat absorption/dissipation in a constant temperature as a temperature standard. <P>SOLUTION: The compression type heat pump carries out a heat cycle on the basis of temperature characteristics produced by atmospheric temperature and latent heat storage material. A heat exchanger carrying out heat exchange with a hot fluid passing through the latent heat storage device is provided in a path from the compressor to a condenser, and a control board is provided, indicating temperature control of heat circulation by a detected temperature value. Correspondence to a load is carried out by adjusting a flow rate of the hot fluid of the heat exchanger, or by efficiently recovering atmospheric heat and storing it as heat in the small and large capacity latent heat storage device. COP is improved by 25% or more in comparison to a conventional one by using a cycle reducing work of the compressor. <P>COPYRIGHT: (C)2010,JPO&INPIT
