District cooling creates economies of scale that drive efficiency, balance electric loads, and reduce fuel costs. In a district cooling network, chilled water is produced or supplied from a central plant and then transported through insulated pipes to homes, offices, hospitals, industrial sites, or other buildings that need cooling. As the cold water flows through the buildings, it absorbs heat. Next, the warm water is recirculated back to the central plant through a closed loop return line.
By aggregating the cooling requirements of an entire network of buildings, rather than cooling each building separately, district cooling improves efficiency, reduces fuel costs, and makes it possible utilize sustainable technologies such as free cooling from lake, sea, or recovered grey water. SWEP offers durable, compact, modular solutions for district cooling.
Heating and cooling from a district or local system scan be distributed to individual buildings through the heat exchangers within the buildings’ HVAC systems. District heating makes it possible to use a variety of conventional and carbon-neutral energy sources to generate heat for residential or commercial facilities.
Supported by SWEP BPHEs, heat can come from geothermal or solar energy, from waste incineration, or from recovering waste heat. By making networks more efficient, BPHEs reduce both the demand for and cost of energy.
The B649 is a single-phase BPHE designed especially for district heating and cooling applications, where it can be used as a pressure breaker between the plant and the residential or industrial building’s substations. The B649 is an efficient, compact BPHE optimized for close temperature approaches at high operating pressure. DN 150 ports enable a complete conversion to BPHEs in district heating and cooling networks..
