A method and apparatus of purifying contaminated liquids employing a particulate filter and a membrane in combination. The particulate filter and membrane are disposed in a unitary container with the membrane being located downstream of the particulate filter. During the process of purifying a contaminated liquid, the membrane causes a back pressure to be exerted on the particulate filter thereby providing substantially even flow of liquid through the particulate filter and minimizing problems associated with uneven flow such as channeling, piping, purging and tunneling. An improved method for cleaning the liquid purification apparatus is also disclosed. The cleaning method preferably employs a gas such as air for scouring the particulate filter and the membrane in a single operation.

Method and apparatus to extract heat by transferring heat from hot compressed refrigerant to a coolant, such as water, without exceeding preselected temperatures in the coolant and avoiding boiling in a water system by removing the coolant from direct or indirect contact with the hot refrigerant.

Heat reclaiming method and apparatus

This invention relates to heating and cooling systems and more particularly to an improved system utilizing a Stirling Cycle engine heat pump in a refrigeration cycle.

Economizer refrigeration cycle space heating and cooling system and

A thermal energy storage system including a thermal energy storage tank and a pair of thermal energy exchange tanks disposed in a different horizontal plane than the thermal energy storage tank. Each of the tanks contain a heat exchange medium and are in fluid communication with each other for circulation of the heat exchange medium between the exchange tanks and the storage tanks by convection. The exchange tanks contain a heat exchange coil which is in fluid communication with a first heat exchanger for heating or cooling the medium in the exchange tank. The storage tank is in fluid communication with a second heat exchanger for the transfer of the heat exchange medium therebetween to heat or cool a structure. The system is disposed beneath the ground adjacent the structure being heated or cooled and an envelope of non-coherent material is disposed about the system to provide a corrosion resistant barrier between the tanks, and the adjacent earth and to act as a conduit for the transfer of thermal energy between the system and the surrounding earth.
