摘要:
The aim of the invention is to improve a refrigerating installation in such a way as to achieve high operating reliability, and savings in terms of energy and cost, in cooling circuits containing a cooling agent (cooling sols). To this end, said refrigerating installation is provided with frequency-controlled cooling units (11) in the form of modules comprising an integrated two-stage evaporator provided with a liquid supercooler and a suction vapour superheater (4/5).

The invention relates to a modular climate control system (10), particularly for generating cold and/or heat, comprising one or more modules (M1, M2,..., Mn), a working medium or coolant being condensed, liquefied, relieved and re-evaporated in a circuit in said modules (M2,..., Mn), and the heat and/or cold generated in the process being delivered to corresponding secondary circuits via heat exchangers. High flexibility in the use of the system, and tremendous simplification in the set-up and modification are achieved in that a common collector (K) comprising collector tubes (21,..., 24) is provided for several modules (M1, M2,..., Mn), the modules (M1, M2,..., Mn) being detachably connected to said collector, and said collector connecting the modules (M1, M2,..., Mn) to the respective common secondary circuit.
摘要:
The invention relates to a system for refrigeration, heating or air-conditioning technology, particularly a refrigeration system (40), comprising a working medium circuit, which has a compressor (12), a condenser (11), an expansion valve (15), and an evaporator (14) connected successively in the flow direction. Particularly stable operating behavior of the system is achieved in a simple manner in that means (25), which thermally couple the liquid operating medium flowing to the expansion valve (15) to the operating medium flowing from the expansion valve (15) to the evaporator (14), are provided in order to maintain the temperature of the liquid operating medium constant.
