<p>PURPOSE:To improve the efficiency of a cooling and heating device by carrying out room cooling is summer season with cryogenic heat accumulated in winter, and in winter, by carrying out room heating with heat accumulated in summer. CONSTITUTION:In summer, the air of high temperatures admitted into the device through an external air intake port 10, passes through a high temperature heat accumulating part 5 while carrying out heating and also passes through a latent heat exchanger 9 and exhaused from the device. Air within a room 2 is passed through an indoor intake port 11 and cooled at a cryogenic heat accumulating part 6, passing through the latent heat exchanger 9 and returning to the room. Upon this occasion, while air within the room 2 is cooled, the humidity within the room increases, and the humid air moves to the high-temperature external air side throuth the latent heat exchanger 9. In winter, low-temperature air entering through an external air intake port 12 carries out cooling while passing the cryogenic heat accumulating part 6, and exhausted via the latent heat exchanger 9. Air within the room 2 enters through an indoor intake port 13 into the high-temperature heat accumulating part 5 wherein the air within the room is heated, and returns to the room 2 via the latent heat exchanger 9. Upon this occasion, the air within the room is heated and humidity within the room decreases, but receives humidity from low-temperature external air and humidified by the latent heat exchanger 9.</p> |
