Title: Controlling method for refrigerant circuit
Inventor: UMEZAWA HIROYUKI
IPC: F25B47/02
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To allow a temperature in a cabinet of a freezer or of a refrigerator not to increase unnecessarily at the time of defrosting operation by further improving a hot gas defrost system in which defrost is performed by permitting a warm refrigerant gas to pass into an evaporator through a circuit bypassing an expansion valve for a predetermined period of time. SOLUTION: A temperature of a refrigerant gas on the suction side of a compressor 11 is detected by a temperature sensor 15 and, in the case where this detected temperature is lower than a defrosting start temperature, an opening degree of an expansion valve 9 is adjusted to a defrost opening degree. This defrost opening degree is set to such an opening degree that a suction pressure of the compressor 11 becomes two to four times higher than that of the compressor 11 at the time of its ordinary operation. When the temperature of the refrigerant gas becomes higher than a defrosting finish temperature in a state that the opening degree of the expansion valve 9 is adjusted to the defrost opening degree, this opening degree is returned to the opening degree at the time of ordinary operation.  In the case where the temperature of the refrigerant gas maintains a lower temperature than the defrosting start temperature in a state that the opening degree of the expansion valve 9 is adjusted to the defrost opening degree and a predetermined period of time elapses, the opening degree of the expansion valve 9 is set to a semi-defrost opening degree. This semi-defrost opening degree means that it is smaller than the defrost opening degree and larger than the opening degree of the expansion valve 9 at the time of ordinary operation.

Title: Ice thermal storage apparatus
Inventor: SEKIYA EIJI
IPC: F24F5/00
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To efficiently heat exchange the ice in a thermal storage tank with warm return water and to improve cold heat supply characteristics to a thermal load by providing at least one return water discharge tube for discharging the return water from the upper part of the tank to the lower part of the tank. SOLUTION: Capillary tubes 12 are suspended as a plurality of return water discharge tubes opened at the lower ends, and the return water 9 from a thermal load 8 is supplied to the upper ends of the tubes 12. Thus, the warm return water 9 from the load 8 flows down through the tubes 12 to the lower part, and hence the ice 6 in contact with the outer surfaces of the tubes 12 is warmed and melted. In this manner, the same number of water tubes as the number of the tubes 12 are generated in the ice 6, and heat transfer surfaces corresponding thereto are appeared. As a result, the water 9 sprinkled from a sprinkling nozzle 10 onto the ice 6 flows into the many water tubes, and hence the water 9 is brought into contact with the ice 6 in a wide area, and the water 9 can be effectively cooled.
