摘要： PURPOSE:To obviate the need to keep the temp. of a space necessary to be heated high and suppress the excessive heating of an unnecessary space by circulating fluid between heat storage material and the surface of a space heater so as to keep the surface of the space heater at a high temp. CONSTITUTION:Heat is stored in heat storage material 2 by the use of midnight power. At the time of space heating, a fan 1 is driven to circulate hot air between the material 2 and the front surface 3 of a space heater and the surface 3 is kept at a high temp. and space heating is carried out by the heat radiation from the surface. By this constitution it is not necessary to keep the temp. of the space high and also to raise excessively the temp. of the space unnecessary to be heated.

摘要： PURPOSE:To perform a proper defrosting operation in respect to an evaporator and always enable an efficient operation with a high capability to be performed by a method wherein an execution of a defrosting operation is controlled in response to a sensing temperature of a temperature sensor arranged in a radiator in an aeration passage in an evaporator. CONSTITUTION:As a heating operation continues, frost gradually adheres to an outdoor heat exchanger 3. An amount of aeration of the outdoor heat exchanger 3 is reduced, a cooling effect in respect to a radiator 32 and electrical devices 33 and 35 is decreased and a sensing temperature of a temperature sensor 36 is increased. As a sensing temperature of the temperature sensor 36 exceeds a set value, a control part 20 returns a four-way valve 2 so as to change over a heating cycle to a defrosting cycle (a cooling cycle). Upon completion of the changing-over of the defrosting cycle, hot refrigerant is supplied to the outdoor heat exchanger 3 and the frost adhered to the outdoor heat exchanger 3 is melted. As the defrosting operation is continued and a sensing temperature of the temperature sensor 36 becomes lower than a predetermined value or a specified time elapses from a starting of defrosting operation, the control device 20 may change over the four-way valve 2 again, finish the defrosting operation and return to a heating operation.

摘要： PURPOSE:To perform the most appropriate and efficient defrosting against an outdoor heat exchanger and always enable an efficient heating with a high capability to be performed by a method wherein a defrosting operation is carried out in response to a difference between a dew point of surrounding atmosphere and a temperature of an outdoor heat exchanger. CONSTITUTION:A control part 10 may detect a dew point DP of surrounding atmosphere with a dew point sensor 7 during a heating operation. A temperature TE of an outdoor heat exchanger is detected by a heat exchanging temperature sensor 6 and the following calculation is carried out with a logical calculation part 11 when its heat exchanging temperature TE is 0 deg.C. alpha=DP-TEo. Then, if a result of calculation alpha is a positive value, a timer 12 is energized and a defrosting operation is carried out after a specified period of time (t) (for example 40 minutes) based on the counter time. The defrosting operation is a so-called inverse cyclic defrosting operation in which a four-way valve 2 is returned and a defrosting cycle (a cooling cycle) is formed. Completion of this defrosting operation can be determined in response to an elapse of a predetermined time.

摘要： PURPOSE: To enable a continuous stable operation of a heat pump to be carried out by a method wherein as a pressure limiting value, a set value having a certain surplus amount is set, and an operation of a compressor is changed over to a non-load operation when a hydrogen gas pressure reaches a set value. CONSTITUTION: When an operation is carried out, a hydrogen gas pressure at a discharging side and a hydrogen gas pressure at a suction side of a compressor 16 are detected by pressure sensors 20, 24, the detected pressure values are inputted to a control device 26 and then a set value which is set in advance and a detected value are compared to each other. Then, an actual pressure value at the discharging side and a set value at a high pressure side are compared to each other and in turn, in the case that the actual pressure value is lower than the set value, a load operation of the compressor 16 is continued and when the value reaches the high pressure side set value, the operation of the compressor is changed over to a non-load operation state. Similarly, as to the pressure value at the suction side, the actual pressure value is compared with the low temperature side set value and when the actual pressure value is lowered, the operation is changed over to a non-load operation. Accordingly, the operation of the compressor 16 is carried out between the low temperature side set value and the high temperature side set value, resulting in that the operation can be continued in a continuous manner without stopping the operation of the compressor.

摘要： PURPOSE: To perform intermittent cooling/heating by stopping the operation of a hydrogen gas transfer unit for a specified time after a specified quantity of gas is transferred and then reversing the transferring direction of a hydrogen gas. CONSTITUTION: Upon finishing transfer of a specified quantity of a hydrogen gas from a heat exchanger 10 for metal hydride to a heat exchanger 12 for metal hydride by means of a hydrogen gas transfer unit (compressor 14, valves 41-44), transfer of hydrogen gas is stopped and connection between the heat medium passages 16, 18 of two sets of heat exchanger 10, 12 and the heat medium passages 26, 22 of an indoor heat exchanging unit 24 and a heat source heat exchanging unit 20 is sustained in the same state as that during hydrogen gas transfer. Upon elapsing a specified time, the hydrogen gas transfer unit is operated to transfer the hydrogen gas from the unit 24 to the heat exchanger 10. At the same time, combination of connection between the passages 16, 18 and 26, 22 is reversed by means of a heat medium passage switching unit (valves 31-38).
