Title: Control system for refrigerating equipment
Inventor: ITO TAKESHI
IPC: F25B41/06
Filed: 1991-10-18
Abstract: PURPOSE:To shift a refrigerating cycle to a steady state early after starting it from its stopping state for a long period by sensing an overheating state of gas at a compressor discharge side immediately before starting a compressor for a refrigerating equipment and controlling the cycle after the compressor is started in response to the sensed result. CONSTITUTION:Before starting an operation of a compressor for a refrigerating equipment, a temperature of discharge gas of the compressor and a temperature of a condenser are first detected by temperature sensors 7, 8, and a difference of both is obtained by a controller 5. Then, an overheating amount of discharge side gas of the compressor 1 is calculated from the difference, and if the amount is smaller than a set value, it is judged that a refrigerating cycle is stopped for a long period and refrigerant is deviated to be existed. At the time of this judgement, an electronic expansion valve 3 is controlled to a large valve travel state by the controller 5. Thus, even if a low pressure side pressure of the cycle is excessively low at the time of starting, it can be early to a steady state after starting the compressor.
