摘要： PROBLEM TO BE SOLVED: To solve the problem that a large power consumption due to a defrosting operation of a refrigerator with a deep freezer expedites global warming and a conventional fluorocarbon refrigerant expedites the global warming.
SOLUTION: The refrigerator with the deep freezer uses a combustible refrigerant such as an isobutane or the like as a refrigerant to suppress the global warming. Thus, a safety of a defrosting heater 30 is improved, and the heater 30 is disposed to be brought into contact with an evaporator 4 to reduce the power consumption.

摘要： PROBLEM TO BE SOLVED: To permit the realization of the high controllability of a temperature and a humidity in a room to be air conditioned efficiently with an inexpensive constitution by controlling the frequency of a compressor and the opening degree of a first choking mechanism. SOLUTION: The equal control range can be maintained by not necessarily regulating the opening degree of a second choking mechanism 6 but only controlling the opening degree regulation of a first choking mechanism 4 and the frequency of a compressor 1 under a condition that the opening degree of the second choking mechanism 6 is fixed, for example. In this case, a latent heat output can be controlled by the increasing or decreasing of the frequency of the compressor 1 and the sensitive heat output can be controlled by the opening or closing of the first choking mechanism 4 as shown by two pieces of arrow signs in a diagram. Accordingly, the sensitive heat output and most part of the latent heat output can be controlled independently by only two control objects or the opening degree of the first choking mechanism 4 and the frequency of the compressor 1 while fixing the opening degree of the second choking mechanism 6 as it is whereby the contents of control can be constituted more simply compared with the complicated conventional temperature and humidity controls, effected by the compressor, the first and second choking mechanisms and the indoor fan.

摘要： PROBLEM TO BE SOLVED: To solve a problem where when a defrosting operation is finished and changed to an ordinary cooling operation in a refrigerator, a startling noise may be generated in a cooler or a refrigerant reservoir after a compressor is started up and amenity of a room space is deteriorated. SOLUTION: A refrigeration cycle is formed by sequentially connecting the compressor, a condenser, a throttling portion, the cooler and the refrigerant reservoir. In the refrigeration cycle, a heater for unfreezing frost attaching to the cooler and a temperature detecting means on a surface of the refrigerant reservoir are provided, and the compressor is started up after lapse of a given time from the defrosting operation by the heater, or operation of the compressor and an inside fan is controlled according to temperature of the refrigerant reservoir detected by the temperature detecting means.
