摘要： PURPOSE:To increase the rise speed of heating operation and to enable regulation of a room temperature to a desired value during steady operation by a refrigerant is fed to an indoor heat exchanger and a floor heating panel independently from each other and an amount of the refrigerant is regulatable. CONSTITUTION:Solenoid valves 31, 32, and 34 are opened, a flow rate control valve 30 is throttled according to heat resistance of a floor heating panel 29, and an indoor fan 24 is run to start combination operation of hot air heating operation by an indoor heat exchanger 25 and floor heating operation by a floor heating panel 29. In this case, the output frequency of an inverter 39 is maximized, and the number of revolutions of the drive motor of a compressor 22 is maximized. The indoor fan 24 is run according to a specified mode, e.g. HIGH. In this case, a refrigerant flows in parallel through the indoor heat exchanger 25 and the floor heating panel 29. However, since an amount of a refrigerant flowing to the floor heating panel 29 is controlled by a flow rate control valve 30, a remaining refrigerant all flows to the indoor heat exchanger 25. Thus, during heating rise operation, a room temperature is rapidly increased from an initial temperature to a set room temperature.

摘要： PURPOSE:To simplify the operation of an environment control apparatus by automatic forming such the indoor environment as the occasion may demand by a simple operation and making possible the temporary change of operational condition, in the environment control apparatus capable of collectively controlling a plurality of environment adjusting devices in accordance with time elapse through the whole year. CONSTITUTION:In the summertime, when an operation instruction is given to an input and output unit 24 by manipulating an operation and stop switch 22 or operating a remote input unit 29 by pressing a switch, a central controller 27 reads out a summer pattern from a memory unit 25 and starts to operate each of environment adjusting devices (3, 5-8) via the input and output unit 24. In this instance, the summer pattern is such that the cooler and dehumidifier 5 are kept ON and the humidifier 6 is kept OFF while the air cleaner 7 and the ventilating fan 8 are kept ON. Accordingly, the heat pump type air conditioner 3 starts cooling operation, and the dehumidifier 5, the air cleaner 7 and the ventilating fan 8 start ON/OFF operation based upon a sensor output. Under such an operational condition, when it is desired that, for example, a room temperature is further lowered by 2 deg.C, the preset temperature can be easily changed by the remote input unit 29.
