摘要： A refrigeration apparatus comprises a machine chamber for containing a compressor, a condenser and others, and a display chamber for accommodating articles to be displayed. The display chamber is constituted by an inner box and an outer box between which a cooling air passage is defined. Defined internally of the machine chamber is a cooler chamber enclosed substantially by a heat insulating material in such a manner as to communicate with the cooling air passage. Disposed within the cooler chamber is a cooling air circulating device and a cooler for causing the cooling air to circulate through the cooling air passage and back to the cooler chamber.

摘要： A defrosting apparatus comprises a housing defining therein a frozen food storage space. Within the housing, air is heated and supplied to the storage space through a hot-air entrance passage formed between a side wall of the housing and one of paired shelf receiving members which cooperate to define the storage space. The hot-air entrance passage incorporates a guide plate having a communication aperture provided at a lower end. The guide plate cooperates with the side wall of the housing and one of the shelf receiving members to force the hot air fed from a ventilating fan to flow first downwardly along the hot-air inlet passage. The hot-air flow is then changed in the flow direction upon passing through the communication aperture so as to flow upwardly. In the course of flowing upwardly, the hot air is fed into the storage space successively through a plurality of inlet ports formed in one of the shelf receiving members.

摘要： A defrosting apparatus including a housing defining a space for accommodating therein articles to be defrosted, a heater for heating the air within the housing, and an air circulation fan for circulating the heated air so that it flows through the space. The apparatus further includes a first temperature sensor disposed on the air outlet side of the circulation fan for sensing the temperature of the outlet air flowing out from the circulation fan to produce a first detection signal, a second temperature sensor disposed at the air inlet side of the circulation fan for detecting the temperature of the air flowing into the circulation fan to produce a second detection signal and a controller coupled to the first and second sensors for receiving the first and second detection signals, respectively, to thereby control the operation of the defrosting apparatus. The controller includes a first comparator for comparing the temperature represented by the second detection signal with a defrosting start temperature to energize the heater when the former is lower than the latter, a second comparator for comparing the first detection signal with a reference signal to selectively deenergize or energize the heater on the basis of the reference signal, and a third comparator for comparing the temperature represented by the second detection signal with a defrosting end temperature to complete the defrosting operation when the former is higher than the latter.
