Frequency Inverters designed for RefrigerationThe main objective in refrigeration and HVAC technology is the reliable supply of refrigeration. In order to ensure intelligent and enery-saving control together, the entire system must be considered.
The intelligent Refrigeration Inverter range FrigoPack FU+ was developed based on decades of know-how in refrigeration technology and therefore stands for reliability, quality and ease of operation.
In addition to reciprocating, screw or scroll compressors, condensing fans are also controlled in an optimum manner. FrigoPack FU+ refrigeration frequency inverters can achieve constant operating pressures even with load fluctuations.FrigoPack FU+ is the ideal frequency inverter for refrigeration and air conditioning systems in supermarkets, hotels, restaurants and food production.
The modular structure of this refrigeration inverter allows a wide range of applications by adding extension modules that are identified automatically by the inverter. The functionality is automatically adapted for various applications .
In its basic version FrigoPackEC FU+ (without modules) controls one refrigeration compressor. Control is based on an external control signal 0…+10 V (or 4...20 mA), e.g. from a WURM control system.
The economy version FrigoPackE FU+ (with module BM-1) is suitable for the control of evaporation and condesation temperatures (tec/tcb control). Information on the pressure needed is transmitted via pressure transmitters and the refrigeration compressors connected (up to 4 with this version) can be speed-controlled effectively and energy-saving.
The functionality of FrigoPack FU+ may be extended with the connection of additional external extension modules, e.g. for monitoring suction gas superheat and discharge gas superheat in order to avoid damage to the compressor.
Module EM-7 e.g. has two inputs for PT-1000 temperature sensors. One PT-1000 senses the ambient temperature for optimized control of condensation, the other is used for suction gas temperature, in order to evaluate superheat and thus protect the compressor.
