New R410A Models Now Available

Tuesday, June 13, 2006

Suwanee, Ga. - Mitsubishi Electric HVAC Advanced Products Division, Suwanee, Ga., has recently transitioned all CITY MULTI® and Mr. Slim® units to R410A refrigerant in support of The Montreal Protocol on Substances that Deplete the Ozone Layer, an international agreement designed to protect the stratospheric ozone layer, according to Paul Doppel, director of product development.

"The addition of the R410A refrigerant to all new HVAC equipment is not only an important step towards improving the performance of our systems, but also demonstrates our leadership role within the industry" says Doppel. "We believed that it was important to make our systems compatible with R410A well before the Protocol's 2010 deadline, providing our end-users with the best product available as soon as possible." CITY MULTI indoor units are compatible with either R22 or R410A refrigerants. The current indoor models have been replaced by the new R22/R410A-compatible indoor units with the "-E" designation at the end of the model number.

Three new CITY MULTI R2-Series outdoor units, which provide simultaneous cooling and heating, and three new Y-Series outdoor units, which offer a choice of cooling or heating, are now available. All six models use R410A refrigerant. Each series now has 72,000-, 96,000- and 108,000-Btu/h-capacity units and all use the R410A refrigerant and also are available with seacoast anti-corrosion protection.

The new CITY MULTI S-Series outdoor units and 6,000 Btu/h capacity indoor units also use R410A refrigerant. The S-Series provides a choice of cooling only or heat pump applications and are ideal for smaller commercial or residential applications because they have a capacity of 48,000 Btu/h. Due to the number of indoor units and a multitude of combinations of indoor and outdoor units, it is impossible to test CITY MULTI systems against current Department of Energy (DOE) central air-conditioning heat pump procedures. Therefore, the DOE has granted Mitsubishi Electric HVAC an interim waiver from the test procedure. New models in the Mr. Slim line of products also have made the transition from R22 to R410A refrigerant. The new M- and P-Series cooling only, heat pump and inverter models have been redesigned to provide new features and benefits, including upgrading to R410A refrigerant.
