A drive circuit is provided.
上記の如き従来のユニット型冷房機を複数台用いて並列
運転する場合、それぞれのユニット型冷房機の温度検出

計画通りの温度制御が行なわれなかった。However, although the temperature settings are individually set and temperature control is carried out, due to variations in temperature detectors, even if an attempt was made to control the settings by shifting the settings by 0.5°C, for example, the temperature control could not be performed as planned.
また、複数の並列運転台数たとえば４台に対応して、１

圧を作り、その温度設定に対応してそれぞれのユニット
冷房機を制御する所謂ステンプサーモと称される方法も
ある。In addition, in response to the number of parallel operating units, for example 4 units, 1
There is also a method called a so-called temp thermo, in which temperature setting voltages having temperature differences are created in different temperature swing devices, and each unit cooling device is controlled in accordance with the temperature setting.
しかしこの場合は並列運転をするための特別の装置を必
要とした。However, this case required special equipment for parallel operation.
本考案は上記にかんがみなされたもので、きわめて簡単
な構成で単独運転も、並列運転にも適用できるユニット
型冷房機のコントローラを提供することを目的とするも

調節される。Therefore, the voltage corresponding to the temperature detected by the temperature detector 2 is input to the temperature setting comparator 4, and compared with the set value set by the voltage divider circuit consisting of resistors R6, R7 and variable resistor Vr2. When the temperature detected by the temperature detector 2 is low, the transistor Q3 is turned on and the unit air conditioner 1 is turned on by the relay The unit type air conditioner 1 is turned off, the relay X is turned off, and the unit type air conditioner 1 is in a stopped state, and is adjusted to maintain the set value.
