摘要：
According to this invention, cold is conveyed into a cooling chamber by means of convectors, and fresh air of a higher temperature is supplied in a controlled manner so that the temperature decreases. To avoid power loss due to the quantity of heat supplied, the displaced cold air is channeled towards a heat exchanger in the condenser of the cooling machine. Since the fresh air which circulates is always above 0.degree. C., the humidity content of the fresh air supplied can be controlled and be filtered to remove odors.
