Abstract (en)
[origin: EP2146154A1] The device (13) has a comparing unit (14) constituted of an operational amplifier to compare measured values of characteristics such as downstream temperature (T1) and pressure (P), of fluid such as air (A) or refrigerant (FR), with corresponding minimum and maximum threshold values of the characteristics. An upstream temperature sensor (20) is arranged in upstream of an evaporator (12) along a flow direction (6) for measuring upstream temperature (T2) of an air flow (3) and delivering information (18) that is considered by the device for determining the threshold values. Independent claims are also included for the following: (1) a heating, ventilation and/or air conditioning system comprising an air conditioning loop (2) a method for controlling a fixed capacity compressor.
