Summary

The objective of this work is to validate the working capacity non-pumping pulsating vapor-ejecting and vapor-compression refrigeration machines and to evaluate the feasibility of these systems that only consume thermal energy. Among all the possible cooling cycles, some only use thermal energy in the form of vapor ejection and absorption cycles. But working agent in the vapor generator is provided by the mechanical pump, which consumes electrical energy and is the least reliable element in these cycles. Preliminary researches have shown that it was possible to realize a new vapor ejecting refrigeration cycle in which the regular mechanical pump can be backed up by heat pump action (PHA). Opportunities of applying pulsing systems in refrigerating using heat from geothermal sources as a secondary resource are considered. constructive decisions of schemes with ejectors in the additional contours of a vapor line are considered too.
