Summary

An electrically driven air to water heat pump, offering compressor speed control, motorised expansion valve and a variable speed air flow fan has been designed and tested.

The heat pump system has been fully instrumented and connected, for control and data logging purposes, to a microprocessor based control unit.

By means of suitable control algorithms it has been possible to accurately control the heat pump to optimum design conditions throughout a range of ambient and load energy levels.

Results show that such a control system can result in improved C.O.P.’s when compared to conventional systems.
