    摘要: In an air conditioner separated into an indoor unit and an outdoor unit, a control circuit comprises a three-phase power source connected in common to the indoor and outdoor units, and a signal line led out from two phases of the power source. A contact of an electromagnetic relay energizing a compressor of the air conditioner is connected on the portion of the signal line in the indoor unit in series with a current sensor sensing the current flowing through the signal line, and a contact of a protective relay protecting the compressor is connected on the portion of the signal line in the outdoor unit in series with the electromagnetic relay. A first controller is disposed in the indoor unit for controlling on-off of the relay contact of the electromagnetic relay, and a second controller is disposed in the outdoor unit for energizing the protective relay contact thereby controlling on-off of the compressor.

    摘要: With an air conditioning system a plurality of building areas, for which individual energy accounts have to be rendered, are supplied by a common fresh air supply and cooling installation. The volume flow rates are controlled by one volume flow rate regulator each, the setpoint of which is adjustable through a servomotor. An output signal representing the setpoint of the volume flow rate regulator is generated and is applied to a meter. This provides with sufficient accuracy the distribution of the volume flow rates between the various building areas as a base for the accounting and billing of energy expenses.

    摘要: A thermostat includes a controller configured to control the thermostat, a power supply sensor connected to the controller for sensing a thermostat power source, a wireless transceiver connected to the controller for receiving control information from a remote device and for transmitting information to the remote device, and a battery level indicator for determining a remaining power capacity of the battery. The controller sets a time schedule for enabling the wireless transceiver when the power supply sensor detects that the thermostat power source is a battery. The time schedule is changed to increase a time period between when the wireless transceiver is enabled as the remaining power capacity of the battery decreases.

    摘要: A ventilation system includes first and second blowers connected to a plenum in parallel, with a first motor drive to control a speed of an electric motor of the first blower and a second motor drive to control a speed of an electric motor of the second blower. A controller associated with the first blower is programmed to receive a set point for a controlled variable that is controllable by operation of the first and second blowers, estimate a total air flow required from the first and second blowers to reach the controlled variable set point, calculate a blower speed ratio between a first blower speed and a second blower speed that provides the required total air flow at a minimum power consumption level, and generate commands to cause the first blower and the second blower to operate at speeds resulting in the calculated blower speed ratio.
