Abstract :
The authors present a concentration-changing heat-pump system using nonazeotropic mixtures. In comparison with other systems, it is simple in structure, convenient to operate, and has a wide range of modulation. The new system, which can automatically change the composition of a mixture in the cycle according to the variation in the indoor-air or return water temperature, has special advantages for heating engineering
