Title:
THERMAL REFRIGERATION DEVICE OR HEAT PUMP
Document Type and Number:
WIPO Patent Application WO2005066555
Kind Code:
A3
Abstract:
The invention relates to a thermal refrigeration device or heat pump, which utilises a partial recycling of waste heat. Said device comprises an evaporator (1), which is preferably thermally coupled to a first heat exchanger (1w) and a condenser (2), which is preferably thermally coupled to a second heat exchanger (2w). The aim of the invention is to obtain a maximum degree of efficiency even at a low heating temperature, by the partial recycling of the inherent waste heat with a simple and space-saving construction. To achieve this, the device is equipped with a pressure booster unit (3), which contains the liquid adsorption or absorption agent, is traversed by a coolant, connects the evaporator (1) to the condenser (2) and is configured from a container of any shape. Said pressure booster unit (3) is thermally coupled to a third heat exchanger (3w), which is traversed by a gaseous or liquid heat transfer medium (4) that is conducted alternately through a heated (5) and a cooled (6) region.
