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.
