BL Series AISI 316 Stainless Steel Plates Copper Brazed Plate Heat Exchanger for Absorption Chiller

Absorption Chiller
If district heat or waste heat is available, for example from waste disposal, there is another possibility for comfort cooling with the absorption chiller. This is an example of the kind of system optimization Baode excels in. We have the knowledge and just the right equipment for providing solutions with both economical and environmental benefits. In this application the CFC/HCFCs influencing the ozone are exchanged to for example water and lithium bromide, both environment-friendly. In the evaporator the refrigerant (water) takes up heat/energy from the connected system, thus cool-ing the air conditioning circuit in a heat exchanger. The refrigerant enters the absorber as low-pressure vapor, where the liquid solvent (lithium bromide) absorbs it. The pump increases the pressure and the mixture continues to the interchanger where it is preheated in for example a Plate Heat Exchanger . Using the district heat, the refrigerant is boiled off from the solvent in the regenerator. The high-pressure vapor is sent to the condenser, where heat is emitted during the refrigerant’s condensation.

Working Principles
The heating surface of liquid heat exchanger consists of thin corrugated metal plates stacked on top of each other. Channels are formed between the plates and corner ports are arranged so that the two media flow through alternate channels, always in counter-current flow. The media are kept in the unit by a brazed seal around the edge of the plates. The contact points of the plates are also brazed to withstand the pressure of the media handled.

Standard Design
The plate pack is covered by cover plates. Connections are located in the front or rear cover plate. The channel plates are corrugated to improve heat transfer efficiency and to make them rigid.

Advantages of Brazed Plate Heat Exchangers in Industry and HVAC&R
The Baode Brazed plate heat exchangers (BHE) have several advantages over traditional heat exchangers in Industrial and HVAC&R Applications.
– The high heat transfer efficiency of the BHE makes it extremely compact and also easy to install in places where space is limited.
– The unit has no gaskets and is therefore suitable in applications where temperature and/or pressure is high e.g. in district heating.
– The Baode supply system reassures that, no matter where you are on the globe, the BHE units are available with a very short delivery time.
