Industrial ammonia heat pumps and their challenges.

Author(s) : PACHAI A. C.

Summary

Industrial heat pumps systems based on ammonia (NH3) as a refrigerant have gained a lot of attention. In fact ammonia has proven to be an efficient heat pump fluid. The challenge to produce a new heat pump is not without pitfalls and should be considered very carefully. The paper covers considerations taken when designing and planning production of heat pumps for industrial applications. Main focus is off course including the whole cycle but a lot of attention has to be put on the selection of measures on how to obtain in the most efficient way all heat from the cycle. Also possible heat sources are discussed. There are a number of low hanging fruits that are very often not included in the considerations. How can heat pumps be used in plants where there is also used other sources for heating such as gas and oil? Are ammonia heat pumps competitive with these systems?
