摘要： PURPOSE:To completely balance the air quantities of feed air and exhaust air systems and to stabilize the indoor pressure and to save energy by using the static pressure control of a blower using a static pressure sensor in combination with the air quantity control of the blower using a feed air speed sensor and an exhaust air speed sensor. CONSTITUTION:A feed air speed sensor VS for detecting the feed air passing quantity and an exhaust air speed sensor VR for detecting the exhaust air passing quantity are provided at sufficiently current form-shaped positions of a feed air system and an exhaust air system, and a static pressure sensor 7 is disposed at the terminal end of a feed air duct 3 of the feed air system. On the other hand, a feed air quantity control signal for controlling the rotational speed of a blower 5 is supplied to the blower 5 so as to make constant the static pressure within the duct 3 by the detection signal from the sensor 7, and detection signals from respective air speed sensors are compared with each other, and an exhaust air quantity control signal for controlling the rotational speed of a blower 6 so that respective passing air quantities assume values within the range of preset values, is supplied to the blower 6. As a result, the air quantities of the feed air system and the exhaust air system can be completely balanced, and the indoor pressure can be stabilized and energy can be saved.

摘要： PURPOSE:To stabilize the indoor pressure and to save energy by controlling the air quantity so as to substantially keep the balance between the air quantities of the air feed system and the air exhaust system by providing a feed air speed sensor and an exhaust air speed sensor. CONSTITUTION:A feed air speed sensor VS for detecting the feed air passing quantity and an exhaust air speed sensor VR for detecting the exhaust air passing quantity, are provided at sufficiently current form-shaped positions of the feed air system and the exhaust air system. On the other hand, a relationship between the feed air quantity when a blower 5 has been controlled, and the static pressure within a duct 3, is sought beforehand and the resistance of the device is set. Thus, the intersecting point between the detected air quantity value due to the sensor VS and the above described resistance of the device, is sought, and a feed air quantity control signal in correspondence with the intersecting point, is supplied to blower 5. Furthermore, the detection signals from the sensors VS and VR are compared with each other, and an exhaust air quantity control signal for controlling the rotational speed of a blower 6 so that respective passing air quantities assume values within a predetermined range, is supplied to the blower 6. As a result, the air quantities of the feed air system and the exhaust air system are completely balanced, and the indoor pressure can be stabilized and energy can be spared.

摘要： PROBLEM TO BE SOLVED: To prevent the circulation of a refrigerant from being stopped by opening a valve body of an expansion valve fully and forcibly when the temperature on the side of a refrigerant liquid falls below a set temperature during the heating operation or exceeds a set temperature during the cooling operation regardless of a difference in temperature between that on the inlet side of the refrigerant and that on the outlet side thereof to heat exchangers of fan coil units. SOLUTION: Fan coil units 2 are each provided with a temperature sensor 8 which always measures temperature on the side of a refrigerant of heat exchangers of fan coil units 2 to transmit an electrical signal when the temperature measured exceeds a value set during the cooling operation or to transmit an electrical signal when the temperature measured falls below the set value during the heating operation. A controller 9 is provided to energize an expansion valve 21 for controlling the supply of the refrigerant by a signal from the temperature sensor 8 to open a valve body thereof fully during the cooling and heating operations separately.

摘要： PROBLEM TO BE SOLVED: To enable prevention of insufficient heating due to the shortage of a refrigerant liquid. SOLUTION: A temperature sensor 72 is provided and always measures temperature on the outlet side of a refrigerant of a heat exchanger of a fan coil unit for each of the fan coil units 2 of rooms during the heating operation to output a signal when the temperature falls below a set value. A controller 7 is provided to monitor an output signal from the temperature sensor 72 at each fixed time and energizes an expansion valve 21 for controlling the supply of the refrigerant to the heat exchanger when the signal is inputted within the monitoring time to open a valve body thereof.

摘要： PROBLEM TO BE SOLVED: To prevent a stopping of circulation of refrigerant without using any liquid receiver against a fast reduction in load at an indoor device in an air conditioning system in which refrigerant is automatically circulated. SOLUTION: A plurality of air conditioning devices 1 are installed at an area to be air conditioned and an absorbing-type freezer 2 is arranged at a higher location than the air conditioning devices 1. A radiator 8 in an evaporator 7 of the absorbing type freezer and a heat exchanger 3 in each of the air conditioning devices are connected by a refrigerant liquid pipe 10 and a refrigerant gas pipe 11 so as to form a refrigerant circuit, wherein the refrigerant gas is condensed in the radiator 8 and refrigerant liquid is evaporated in the heat exchanger 3 to cause the refrigerant to be automatically circulated in the circuit. A differential pressure sensor 12 for use in sensing a pressure difference between the insides of both pipes near each of their lower ends is arranged between the refrigerant liquid pipe and the refrigerant gas pipe. This sensor 12 temporarily stops an operation of the absorbing type freezer as a lower pressure differential value than a predetermined set value and after elapsing a certain period of time, the operation is started again.
