Absorption heat pump schematic

With the development of science and technology, heat pump technology has also been applied more and more widely. Heat pump technology is the use of natural air, soil and other natural resources to obtain low-level heat, and then through a series of effects to generate high heat energy. Today's main introduction is the principle of absorption heat pump. Absorption heat pumps can be categorized into two types. The following will introduce the two types of absorption heat pumps.

The first type of lithium bromide absorption heat pump principle introduction: The first type of lithium bromide absorption heat pump unit is a high temperature heat source (steam, high temperature hot water, fuel, gas) as the driving heat source, lithium bromide solution as absorbent, water as refrigerant, Recycling heat energy from low-temperature heat sources (such as waste hot water), and preparing the required process or high-temperature heating medium (hot water) for heating to realize the equipment for transporting heat energy from low temperature to high temperature. The heat pump consists of generators, condensers, evaporators, absorbers, and heat exchangers, as well as other components such as suction devices, shielding pumps (solution pumps and coolant pumps) and other auxiliary components. The suction device removes the non-condensable gas in the heat pump and keeps the heat pump in a high vacuum state.

The second type of lithium bromide absorption heat pump principle introduction: The second type lithium bromide absorption heat pump unit is also the recovery of the use of low temperature heat source (such as waste hot water) heat energy, to obtain the required process or heating high temperature heat medium (hot water), to achieve Equipment for transporting thermal energy from low temperature to high temperature. It uses a low-temperature heat source (waste hot water) as the driving heat source, and uses a low-temperature cooling water to produce a heat medium (hot water) having a higher temperature than the low-temperature heat source. It differs from the first type of lithium bromide absorption heat pump unit in that it does not require a higher temperature heat source to drive but requires a lower temperature cooling water.
