Waste Heating Pump

A New Generation of Waste Heating Pump-Heating Unit Heating Record

In mid-November 2022, the office building of the factory in Hebei, China ushered in the winter heating season, and the indoor temperature was stable at around 25°C.

Unlike previous years, this year's heating does not burn boilers or consume electricity, but adopts the latest generation of technical equipment: low-temperature absorption heat pumps.

The special thing about this equipment is that it consumes very little energy. It uses 35°C waste hot water to drive and operate, and can produce 50°C hot water, which is more than enough to heat an office building of more than 3,000 square meters!

According to calculations, the office building heating costs alone can save a lot of money every year. After a one-time investment in renovation and installation, you can enjoy warm winters safely in the next 10-15 years.

More meaningful than saving money, heating energy consumption and emissions can be reduced by more than 90%! It is a veritable "micro-carbon" technology.

The low-temperature absorption heat pump is the latest generation of absorption lithium bromide heat pump technology. It can use 40°C waste heat as power to drive work, and is very suitable for central heating in northern winter.

First, ubiquitous industrial waste heat can be used to provide centralized heating for factories, parks, surrounding communities and towns, greatly reducing energy consumption for heating in winter.

Second, the 40°C return water from the municipal central heating pipe network can be used to drive the equipment to operate, and then provide heating again after raising the temperature. Without increasing primary energy consumption, it is expected to increase the heating area and heating capacity of the heating company by 20%. .

In fact, in the winter of 2021, this technology has been applied to a chemical plant, and its desulfurization slurry will release waste heat throughout the year, which needs to be cooled by cooling towers. The factory uses a low-temperature absorption heat pump, which can recycle all the waste heat from the cooling tower at 40°C-50°C to provide centralized heating hot water for the factory and surrounding areas. It also reduces the process temperature to 30°C to achieve environmentally friendly whitening. Request, kill two birds with one stone!

By utilizing low-temperature absorption heat pump technology, industrial waste heat that was originally emitted in vain, useless, and even costly to process, has become usable renewable energy! If the industrial waste heat of the whole society is recycled, the economic value and social significance that can be created will be huge!
