PURPOSE:The titled device capbale of heating or cooling quickly the inside of a chamber, obtained by fixing plural fans to a heating or cooling chamber at both the top ends, sending a gas along the side wall of the chamber, circulating it enforcedly and uniformly. CONSTITUTION:For example, one clock frozen pork roast is placed on each of the thawing shelf 7, and the fan F is operated so that air is forcedly circulated. While, in the heat exchanger 40, water jetted or sprayed from the jetting nozzles 45 attached to the jetting pipe 44 is sprayed on the evaporating pipe 47, and a refrigerant, especially high-temperature refrigerant is circulated through the pipe 47. Air introduced from the exhaust vent 4 to the inlet 42 is sent in the arrow direction A to the heat exchanger 40, it is sufficiently subjected to heat exchange and cooled to a saturated state during the travel. It is sent from the outlet pipe 43 to the duct 3, water drops are removed by the cyclone 9, and it is forcedly introduced from the top open part 2 to the thawing chamber 1. The air sent to the chamber 1 is uniformly dispersed in the arrow direction to the chamber 1 by the perforated panel 6, brought into contact with the frozen roast block, subjected to heat exchange, and it is thawed under extremely mild conditions. |
