Absorption heat pump schematic

With the development of science and technology, heat pump technology is also more and more widely used. Heat pump technology is a use of natural air, soil and other natural resources to obtain low heat, and then through a series of high heat generated. Today mainly introduces the absorption heat pump principle. Absorption heat pump can be divided into two categories, the following will introduce the two types of absorption heat pump principle. The first type of lithium bromide absorption heat pump principle: The first type of lithium bromide absorption heat pump unit is a high-temperature heat source (steam, hot water, fuel, gas) as the driving source of heat, lithium bromide solution as absorbent, water as a refrigerant, Recycling low temperature heat source (such as waste water) heat, to obtain the required process or heating with high temperature heat medium (hot water), from low temperature to high temperature heat transfer equipment. Heat pump by the generator, condenser, evaporator, absorber and heat exchanger and other major components and extraction device, shielding pump (solution pump and refrigerant pump) and other auxiliary components. The air extraction unit removes the non-condensable gases from the heat pump and keeps the heat pump in a high-vacuum state all the time. The second type of lithium bromide absorption heat pump principle: The second type of lithium bromide absorption heat pump unit is the heat recovery of low-temperature heat sources (such as waste water), the preparation of the required process or heating with high temperature heat medium (hot water), to achieve From low temperature to high temperature heat transfer equipment. It uses low-temperature heat source (waste hot water) as the driving source of heat, in the use of low-temperature cooling water under the conditions of preparation than the low temperature heat source temperature medium (hot water). It differs from the first lithium bromide absorption heat pump unit in that it does not require a higher temperature heat source to drive it but requires lower temperature cooling water.
