Heating/cooling system i.e. variable refrigerant flow system, operating method for interior space, involves transferring cold from weather-independent energy sources over heat exchanger into heat

摘要

The method involves producing heat/cold of a compression refrigeration machine from outside air and by waste heat of motors. The heat, in a heating mode, is transferred from weather-independent energy sources e.g. groundwater wells, into a geothermal system over a refrigerant circuit (23) and is output from the circuit with a higher temperature level by a heat-exchanger. The cold, in a cooling mode, is transferred from the sources over the exchanger into heat and is introduced for supporting air conditioning in the circuit. The heat is derived from the refrigerant circuit and stored in earth. An independent claim is also included for an arrangement for operating a heating/cooling system for an interior space.
