EcoPac – High temperature low charge Isobutane heat pump.

Number: 0092

Author(s) : ÖLEN V., GRANRYD E., PALM B., ANDERSSON K., NOWACKI J. E.

Summary

The EcoPac project comprises of the development and evaluation of a heat pump with low charge of R600a (isobutane), optimized for a low temperature lift. The cold side operates at temperatures of 15 to 35 ⁰C and the high side temperatures are 50 to 70 ⁰C. This paper describes the heat pump when used as a standalone unit with water as heat transfer fluid. The following results have been attained with a charge of 120g of R600a:
• output of heat in the range of 2 up to 12 kW,
• a maximum output of heat of 1kW per 10 g of refrigerant and
• Coefficient of performance of 3,3 up to 11 depending on operating condition.
