Title: Heater
Inventor: OTAKE TATSUNORI
IPC: F24D7/00
Filed: 1988-05-31
Abstract: PURPOSE:To prevent the heat breakdown due to abnormal heating of refrigerant and improve the stabilization of a cycle, by performing continuous operation on a cycle of the combustion which is large in quantity for a specified time after the quantity of combustion is changed over when the quantity of combustion of a refrigerant heater is changed from large to small and then changing over to the cycle of the combustion which is small in quantity. CONSTITUTION:A required circulation quantity of refrigerant, which is not abnormally heated with a refrigerant heater 1, is defined as G while the cycle of opening/closing time is defined as T. When the combustion quantity of a burner is increased, the cycle T is reduced while G is increased. When the combustion quantity of the burner is reduced, attempts must be made to extend the cycle T, reduce G, prevent abnormal heating of refrigerant with the refrigerant heater 1 in terms of the combustion quantity of each burner, and produce the equilibrium between the quantity of refrigerant to be forcedly fed to a radiator 6 from the refrigerant heater 1 and condenced and the inflow of the condenced liquid refrigerant from the radiator 6 to a liquid receiver 2, thereby enabling to prevent the hunting of the cycle pressure. When the combustion quantity of the burner is changed over from large to small, the refrigerant of the radiator 6 is returned to the liquid receiver 2 on a short cycle of an ON/OFF valve according to the prior art practice. According to the present invention, however, the above performance is continued for a specified time and after a specified time, the cycle of the ON/OFF valve 4 is extended, thereby preventing the rise in the cycle pressure caused by the continuous operation after the combustion quantity is switched over under the increased distribution of the refrigerant.
