PRODUCTION OF HEAT WITH A HEAT PUMP USING A SPECIFIC MIX OF WORK FLUIDS

摘要

specific disclosure.the present invention provides a process for the district.a local heating using a heat pump operatingtaking the heat out of the premises to be heateda fluid whose temperature is between 0 and 20by providing, to the premises to be heated, the heat ahigher temperature level, the heat pump operationwith a mixture of fluids which do not form an azeotrope.the mixture containing at least two components including aas main constituent is basic and at leasta second component, characterized in that it hasa second component with a critical temperature abovethe critical temperature of the component and the base, the differencethe critical temperature of the core and the componentthe second component is the critical temperature of at least- and the molar concentration of the second component in thethe mixture is between 0.5 and 20%.
