Abstract (en)
[origin: WO9303311A1] Temperature control apparatus (1) for controlling temperature in a building comprises a central unit (2) for supplying a heat transfer medium, namely, water to a remote unit (3) through a circulating circuit (4). The central unit comprises a reversible refrigeration circuit (8) comprising a main heat exchanger (11) which exchanges heat between the refrigerant medium and the heat transfer medium. A return temperature sensor (32) monitors the return temperature of the heat transfer medium to the main heat exchanger (11), and a differentiating circuit (34) determines the rate of exchange of change of the return temperature with respect to time. A microprocessor (26) controls a compressor (12) of the refrigeration circuit (8) for varying the energy output of the refrigeration circuit (8) in response to the rate of change of the return air temperature.
