SHORT DESCRIPTION OF THE SYSTEM
Solar Heat Exchangers worked with the professional team at RSV Engineers. Solar Heat Exchangers designed, supplied and installed a 14,200L hot water system for the Middelpunt Industrial Change House in Limpopo.
Established in 1987, Solar Heat Exchangers is a leading South African specialist in energy efficient water heating applications and is proud of its reputation for technically superior products and quality workmanship. The company’s products cover various renewable energy and energy efficient water heating applications including process heat, sanitary hot water, space heating and swimming pool heating using solar, heat pumps & gas as a heat source. Solar Heat Exchangers is a wholly owned subsidiary of Solsquare, a company established in 2007 specialising in Solar Photovoltaic system design and installations.
CHARACTERISTIC’S OF THE SYSTEM
The hot water system was designed by Solar Heat Exchangers. A 14,200L solar hot water storage modular system was designed for future upgradeability to 28,400 & 42,600L capacity.
PLANT ROOM FOR STORAGE VESSEL
The plant room houses 5 x 14,200L hot water storage tanks in series – 3 intended to be solar heated tanks with 2 electrically backed up tanks. The last 14,200L solar tank pre-heats the electrical tanks.
MODULAR SYSTEM DESIGN
At time of design and installation, the mine was not fully staffed. The budget did not allow for a ‘full capacity’ system so it was designed as a modular system. Pipe sizes were installed to accommodate the future system. The heat exchanger is a plate and frame type exchanger which can be augmented as per expanding requirements. Only pumps would need to be upsized as the systems closed circuit volume increased in time.
FRAMES FOR THE PANEL INSTALLATION
An ideal winter time solar collector angle was chosen although the existing roof pitch might well have sufficed. The pitched roof frames however act as additional fall barriers for any service & maintenance staff working on the roofs. The 90 flat plate solar collectors are mounted on the roof and plumbed in 9 banks of 10 collectors. The arrays are sized with even banks for ease of balancing flow through a complex closed circuit pipe network.
MAINTENANCE & LOCAL TRAINING
Solar Heat Exchangers trained local workforce to do on site annual maintenance of the system.
Note: At time of the solar system commissioning the tanks were not cladded.
