<p>A control system 21 for a heat pump 3, where the control system comprises means for determining a dew point which may include a temperature sensor 23, a relative humidity sensor 25, and a processor for determining the dew point based on the measured temperature and relative humidity. Preferably, a wireless transmitter is provided for transmitting data derived from the sensors. A control signal generator is provided for generating a signal to control the heat pump based on the determined dew point. The present application also relates to a method of controlling a heat pump, and to a heat transfer system 1 comprising a control system for controlling a heat pump based on a determined dew point. The heat transfer system comprises a central heating system having at least one radiator 5, such as an underfloor heating system, where the heat pump extracts heat from a fluid circulated through the central heating system, In a further aspect, a heat transfer system is specified comprising at least one internal heat exchanger operable as a heat source, a heat pump, and an external heat exchanger (39, fig.2) operable as a heat source or a heat sink.</p> |
