Cooling system using low potential and high potential energies

摘要

A cooling system which includes an occluding section for occluding vaporized cooling agent by means of an occluding agent so as to ensure continuous evaporation of cooling agent in the evaporating section. The system includes a high pressure and low pressure recovery sections for recovering the cooling agent from the occlusive agent by applying heat thereto. When a low potential energy is available, the occlusive agent is passed from the occluding section only to the low pressure recovery section, but when a high potential energy is to be used, it is passed through the high and low pressure recovery sections in this order.
