A development project to design and build up one heat pump.

The designed heat pump unit has to meet following requirements:

— refrigerant R1234ze;

— as high heating capacity as possible;

— maximum dimensions of the unit 20 m x 10 m x 8 m (length x width x height) approximately;

— maximum heating outlet temperature ≥ 95 ºC;

— sewage water to evaporator.

Approved compressor type: turbo compressor.

The heat pump unit shall be designed so that:

(a) inlet temperature of sewage water to evaporator varies between + 6-20 ºC;

(b) inlet temperature of district heating water to condenser varies between + 37-60 ºC.
