摘要： It is possible to accurately and easily detect an abnormality in an electronic expansion valve without cutting or separating an electronic expansion valve from a cooling medium circuit. When an excitation pulse current from a drive circuit is output, a magnet rotor of an electronic expansion valve rotates. A hall element detects the position change of the magnet rotor at this time as detection pulses. The number of the detection pulses at this time is sent to a first up-down counter via an amplifier and a rectifier and is counted. The number of excitation pulses is also counted by a second up-down counter. The abnormality detection element judges that there is normal operation when the two count numbers of the first and second counters are in agreement, and that there is an abnormality when the two are not in agreement.

摘要： A refrigeration cycle is a closed cycle constituted by a variable power compressor, a four-way valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger. Air-conditioned air is supplied from the refrigeration cycle to a plurality of rooms to be subjected to air conditioning through a supply duct at a portion near a supply opening for supplying the air-conditioned air to a corresponding one of the rooms and controls a flow amount of the air-conditioned air supplied from the supply opening. Air is returned from each room to the refrigeration cycle through a return duct. The indoor heat exchanger of the refrigeration cycle has a temperature sensor for detecting the temperature of the indoor heat exchanger. A system controller controls a drive frequency of the variable power compressor of the refrigeration cycle in accordance with a difference between the temperature of the indoor heat exchanger detected by the temperature sensor and a preset temperature of the indoor heat exchanger.

摘要： An air conditioning system comprising an outdoor unit in which a compressor is driven by the power supplied from a variable-frequency power supply and a plurality of indoor units operatively connected to the outdoor unit. Each indoor unit has a circuit for generating a frequency signal to be applied to the variable frequency power supply of the outdoor unit in response to a set room temperature and a temperature detected. In response to the frequency signals transmitted from the indoor units, the control unit of the outdoor unit detects a maximum frequency, a minimum frequency and the number of operating indoor units and determines the operating frequency of the variable frequency power supply in response to the maximum and minimum frequencies and the number of operating indoor units. The control unit includes a decision circuit which responds to the frequency signals transmitted from the indoor units so as to detect a maximum frequency, a minimum frequency and the number of operating indoor units, a circuit which responds to thus obtained maximum frequency and the number of operating indoor units so as to determine an operating frequency which is to be corrected, a circuit for obtaining a correction value, which is used to correct the operating frequency, in response to the difference between the maximum and minimum frequencies and a circuit for determining an operating frequency to be applied to the variable-frequency power supply by subtracting the correction value from the operating frequency to be corrected.
