MCHE - microchannel heat exchangers improve HVAC systems





MCHE - microchannel heat exchangers improve HVAC systems

The demands on heat exchangers is increasing. The newest, strongly efficient systems are those heat exchangers with tube’s diameter less than one millimetre. Such a heat exchangers are made by Sanhua according to the latest energy efficiency standards.

The tiny MCHE with micro-meter tubes need only about half as much space as other solutions and weights much less. It reduces the quantity of used refrigerants providing at the same time better heat transfer. Such installed Microchannel Heat Exchangers, MCHE are more cost-effective and environmentally friendly.

Thanks to its fine tubes with small internal volume of MCHE consume by up to 30% less refrigerant than other devices. Sizes up to 4,000 x 1,900 mm are available, and the weight is only about 20% of a finned tube heat exchanger. At the same time the MCHE achieve greater transfer of thermal energy through improved refrigerant flow at the micro level. MCHE are more efficient, more compact and lighter.

For users of Sanhua MCHE this results in many benefits: installation of MCHE in applications like evaporators, heat pumps or air conditioning with improved efficiency by 30% and reduced refrigerant charge up to 30%.

The power consumption is so low that environmental regulations are fully complied and the CO2 footprint is reduced to minimum. Producers consume less raw materials in the production and more products can be transported in less space and store.

Additional advantage is the accurate and reliable temperature control system that is used in the precise cooling or refrigeration to protect sensitive equipment and generally contributes to the energy efficiency of HVAC-R systems. The space-saving design allows manufacturers a slim and attractive design of their products such a heat-pumps. It consists of 100% of aluminium, which prevents rust formation and guarantees a long life of the plant. In addition, the device is completely recyclable.

Sanhua is the global market leader in micro channel heat exchangers with 1.5 Million units produced in 2014 (Hangzhou, China) far beyond its competiors producing in Europe or exporting to the Eurozone.

Sanhua is forcasting a production of 2 Millions units in 2015 thanks to its MCHE factory aquisition in the US in 2014 and its brand new facility in Mexico launched end of last year. Sanhua Europe operates through its logistic hub located in Bierun, Poland.  

Over the last 6 years, the MCHE technology has demonstrated its ability in reducing the carbon footprint emissions by lowering the refrigerant charge of heat exchangers, providing higher performance while reducing chillers weight and size and pushing costs down.

Sanhua is seen by its customers as reliable and cost effective and keeps ahead from its competitiors in its ability in mastering all applications at the HVAC&R; starting by the traditional condensing application; but also offering evaporators application in negative temperature for cooling cabinets for instance; evaporators in positive temperature for air conditioners and precision cooling; heat pump heat exchangers for residential, and now scheduling heat pump coils for commercial chillers application (Launch at Mostra Convegno 2016).

Last not least, Sanhua is also at the home appliance industry with its micro-channel heat exchangers – stating a revolution at this business sector as well, by offering higher efficiency energy label at the heat pumps applications.
