摘要： PURPOSE:To enable to secure at all times, stable dwelling characteristic by a mothod wherein a requirement for the change-over between the cooling and heating operations is automatically sensed and a change-over operation between the cold water and the hot water is performed in response to the sensed condition. CONSTITUTION:A control device 17 receives a temperature sensing signal from each of the temperature sensors 16, 16', 16'',... in the rooms, sets the valves 5, 5' to the hot water feeding condition for performing the heating operation and sets the initial value of the fed hot water through the controller 8. In turn, it judges that the cooling is required and sets the initial fed cold water temperature through the controller 8'. In accordance with such a judgement as above, each of the fan coil units 2, 2', 2'',... of the rooms is started to operate. Then, the control device 17 receives the measured values such as interior room temperature or surrounding atmosphere temperature by temperature sensors 16, 16', 16'' and the temperature sensor 15 as well as the measured value of insolation from a pyrheliometer 14 and further receives the measured calorific value of a calory calculator 13, and controls them.

摘要： PURPOSE:To perform the control in consideration of incoming (outgoing) calory in correspondence to the atmospheric temperature condition to prevent the overcooling and overheating of the room by automatically turning OFF the fan when the optimum temperature of supply water combined with the atmospheric temperature varies to the higher value than the predetermined value. CONSTITUTION:A fan coil unit 4 installed in the perimeter of each zone of a large- scale zone, is provided with a fan 13 for blowing out air sucked up through a coil (heat exchanger) 10 connected with a cool and hot water supply pipe 8, a return pipe 9 and a lower suction port 11, from an upper blow-out port 12 through the coil 10. The fan 13 is driven by a motor 14. On this occasion, a water temperature detector 17 for detecting the water temperature at the inlet of the coil 10 is provided in the cool and hot water supply pipe 8, and the motor 14 is turned ON and OFF through a controller 15 in correspondence to the output from the detector 17. That is, when the detected value of the water inlet temperature varies by a certain value from the set value obtained by an optimum combination between the outer air temperature and the cool and hot water temperature, the motor 14 is controlled to be turned OFF.

摘要： PURPOSE:To reduce noise with a simple construction, by a method wherein cooling or heating capability can be varied by changing over the inflow and outflow directions of a refrigerant or hot water passed through a heat exchanger, in a cooler-heating such that a cool air flow or a warm air flow is obtained by a refrigerant or hot water passed through a heat exchanger. CONSTITUTION:Hot water flows from a heat source 11 into an inlet 13 of the heat exchanger 12 through a four-way valve 15 as indicated by solid-line arrows, returns to the heat source through an outlet 14 and the valve 15, while releasing heat at the heat exchanger 12. Then, the valve 15 is changed over to cause the hot water to flow in the opposite direction as indicated by dotted-line arrows. Since the heat-exchanging effiency is largely changed by reversing the flowing direction of the hot air passed through the heat exchanger 12, the heat-exchanging capability can be changed while maintaining the rotating speed of a blower 16 to be constant. A similar effect is achieved also in a cooling operation. Accordingly, the harsh change of noise at the time of changing the rotating speed of the blower can be eliminated, and noise can be reduced.

摘要： PURPOSE:To enable to switch the water channel by opening and closing valves, of which number is less than the number of the water channels, by a method wherein the water channels are formed by the main water channel having a solenoid valve, the sub water channel, reduced in the pressure thereof when the main water channel is opened, and a non-return valve, closed when the pressure of the sub water channel is reduced. CONSTITUTION:When the solenoid valve 11 is opened and water is flowed to the main water channel 9 of the advancing channel of circulation, the static pressure of a throat section at the ramificating point of a shunt 12 remificating the sub water channel 8 for the advancing channel of the circulation is reduced and the pressure at the connecting side of the sub water channel of the shunt becomes lower than the same of the main water channel, therefore, the water at the sub water channel side is tried to be sucked into the main water channel side. However, the non-return valve 13 is provided at the sub water channel 8, therefore, the water in the sub water channel is brought into stopped condition. On the other hand, when the solenoid valve 11 is closed, the non- return valve 13 is opened into the favorable direction thereof and the water is flowed through the sub water channel. By utilizing the shunt 12 in such a manner, one set of the expensive solenoid valve may be saved.

摘要： PURPOSE:To obtain the air-conditioning apparatus achieving a sufficient electric power saving by a method wherein a frequency of the electric power supplied to a centrifugal pump is adjusted so that an opening degree, detected by the opening degree detector for a flow amount control valve, becomes a predetermined value near the value of full opening. CONSTITUTION:Temperature detectors 35, 36 are provided at the blow-off ports of the air conditioners 10, 11 and temperature regulator 37, 38 regulate the opening degrees of the flow amount control valves 13, 14 so that the temperature of cool wind or warm wind becomes a preset temperature. The centrifugal pump 21 is driven by the electric power supplied by a generator 20 which is driven by an internal-combustion engine 19. A signal selector 17 selects a signal having a larger opening degree among the signals from respective opening degree detectors 15, 16 to input it into an adjustor 18. The adjustor 18 controlls the revolving speed of the internal-combustion engine by the signal in accordance with the opening degree of 95%, for example, of the predetermined opening degree near the full opneing degrees of the flow amount control valves 13, 14.
