Requirements concerning the control of heat pumps
Abstract
An adjustment of the heat supplied by the heat pump to the heat requirements is currently made by means of an approach involving an operation of the heat pump during a certain time interval of a heating cycle. The possibility to optimize the operational characteristics of the system with the aid of a continuous control method is investigated, taking into account pressure ratios, the flow volume, rotational speed, and power requirements. It is found that an improved control method would result in energy savings of about 20%. An improvement in compressor efficiency would reduce the energy consumption by another 20%.
