Objective
Aim of the project was the rehabilitation of heat pumps and the associated systems first installed 25 years ago.
The contractual work program was respected only in the case of the first two phases of the project, i.e. phase 1 - demonstration design, phase 2 - confirmation of additional manufacturing cost. The other project phases were considerably delayed : phase 3 - manufacture and assembly of prototype, completion postponed from December 1981 to 15/11/82: phase 4 - experimental test and phase 5 - reporting test and phase 5 - reporting and design for production, from June 1982 to May 1983 subsequently abandoned.
The heat pump systems consists of two gas engines. One powering the heat pump compressor and the other one an alternator feeding the water and evaporator circulation pumps. The thermal output of the system is appr.. 150 kW and the electric output 14 kWe. The Oxford sewer is used as the heat source. The heat pump is working in parallel with the conventional oil fired heating plant of the Nuffield College (400 kW). The heat is used at three different levels (43 - 60 - 71 deg C).
