<p>PURPOSE:To contrive saving of energy as well as prevention of temperature decrease at night by a method wherein air in a space to be heated is heated by a heat pump type heater and the heat of air is accumulated in a heat accumulating material tank under drying the material which absorbs moisture in the air, thereafter, is released at night, in the heating device for greenhouse for agriculture. CONSTITUTION:The air, introduced through an air intake 2, passes through the heat dissipating device 3 of a heat pump and is introduced into the casing 1 of the heat accumulating tank. During this period, the air is heated by the heat dissipating device 3 of the heat pump, therefore, the air heats and dries silica gel 4 in the heat accumulating tank 1 during passing through the silica gel 4 while the heat is accumulated in the tank 1 simultaneously. The air is released into the greenhouse together with moisture being deprived from the silica gel 4. At night, the heat pump 3 is stopped and a fan 5 is driven to heat the air by the accumulated heat in the tank 1 and heat the greenhouse. According to this constitution, energy saving as well as heating at night may be contrived.</p> |
