Design options for increasing the efficiency of an R717 heat pump

Numéro : 1179

Auteurs : MARTIN J.


The price of electricity in the UK is relatively high and the price of gas relatively low. Designers of heat pumps, therefore, face an uphill struggle to design a heat pump which is economically viable compared to conventional gas fired central heating, which also has a relatively low capital cost. A high bar is thus set efficiency-wise in order to attain a reasonable payback period.
This paper will discuss the control of large, river source, ammonia heat pumps for maximum efficiency, with particular reference to the current such project being undertaken in Clydebank. In this case, a desire for boiler back up of the full heating load and a low heat demand in the early phases in the development of the district, led to the hot water circuit configuration of heat pumps and boilers in parallel.
