Abstract

A vapor generating and recovering apparatus for vaporizing a liquid and condensing a vapor, the apparatus including a container having a liquid therein with a heating and cooling system in heat transfer relation with the liquid and vapor in the container. The heating and cooling system includes means to vaporize the liquid; means to condense the vaporized liquid; and, means to compress a refrigerant. The means to compress the refrigerant is in fluid communication on its high pressure side with the means to vaporize a liquid or heat a liquid and on its low pressure side with the means to condense or cool a liquid. The heating and cooling system further includes a complementary condenser system on the high pressure side of the means to compress a refrigerant, discharging its heat external to said apparatus and pump down valve means selectively closeable so that refrigerant can be pumped out of the means to compress a refrigerant.
