PURPOSE:To make it possible to carry out suitable heating even for farm products requiring a high nighttime retained temperature by combining a heat storage tank having a latent heat type heat storing agent with a compression type heat pump. CONSTITUTION:The titled device comprises the heat storage tank 1, the latent heat type heat storage agent 2 accommodated therein, and a heat pump 3. At one opening 11 and another opening 12 of the heat storage tank 1 are disposed heat exchangers 4 and 5 of the heat pump 3, respectively. The compressor 30 of the heat pump 3 is connected to the heat exchangers 4 and 5 through a four-way changeover valve 6. By manipulating this changeover valve 6, the heat exchangers 4 and 5 alternately function as a condenser and an evaporator. As a result, upon the heat storage, air is heated by the condenser of the heat pump 3 and the heat is afforded to the latent heat type heat storage agent 2. Then, the heat is cooled by an evaporator of the heat pump 3 and discharged. Upon radiation, air is cooled once by the evaporator of the heat pump 3 to promote the radiation from the latent heat type heat storage agent 2 and thereafter air is heated by the condenser of the heat pump 3 to heat the room. |
