Published on

Mitsubishi Electric has been designing and manufacturing commercial hot water heat pumps since 1970. Mitsubishi Electric was one of the first manufacturers in Japan to utilize heat pump technology to provide hot water. We were
also the first manufacturer to develop R407C products, which can supply hot wat er of up t o 70º C, high enough to eliminate legionella bacteria.

  2. 2. Mitsubishi Electric - Leading Manufacturer ofHot Water Heat PumpMitsubishi Electric - Leading Manufacturer ofHot Water Heat PumpMitsubishi Electric - Leading Manufacturer ofHot Water Heat PumpOil boiler had been previously installed for more than ten years, andhad a frequent malfunction. When we built a new annex in 2005, wedecided to renew the system. We first thought of the gas system;however, concerning safety and reliability, we decided to use theelectric system. Up to today, we have been using MitsubishiElectric’s Hot Water Heat Pump for more than five years. Nomalfunction has occurred, and we are also satisfied with its safety.Application : Nursing homeCountry : JapanWork : June, 2005Installation : Hot water heat pump 20HP x 1Case StudyOwner’s Voice"Flash-injection Circuit", which is designed for our ZUBADAN CITY MULTI (airconditioning system for cold regions), is mounted in our new Hot Water HeatPump. By utilizing our advanced "Flash-injection Circuit" and the latesthigh-efficient compressor, Hot Water Heat Pump is able to provide hot water of70°C, and produces less capacity drop at low outdoor temperature.Environmental friendly R407Crefrigerant with ZERO ozonedepleting potential is used in theproduct, which reduces CO2emissions compared to that ofgas boilers.Two-phase refrigerant is separated into liquidrefrigerant and gas refrigerant at the point of A.Liquid refrigerant, whose pressure is reduced byLEV (Linear Expansion Valve), exchanges heat inthe HIC circuit and become gas-liquid two-phaserefrigerant. The two-phase refrigerant flows into theinjection port in the compressor for controlling theincrease of the discharge temperature. Thereforethe optimal amount of refrigerant can be providedto the system via the compressor, which makes itpossible to provide hot water of 70 ºC.During defrost operation,two compressors, whichare equipped within oneunit, run alternativelyresulting in less drop inoutlet water temperature.Mitsubishi Electric has been designing andmanufacturing commercial hot water heatpumps since 1970.Mitsubishi Electric was one of the firstmanufacturers in Japan to utilize heat pumptechnology to provide hot water. We werealso the first manufacturer to developR407C products, which can supply hotwater of up to 70ºC, high enough toeliminate legionella bacteria.We quickly rose to the forefront of hotwater supply industry in Japan - aposition we still enjoy today.O u r p r o d u c t s a r e m a i n l y u s e d i ncommercial applications, such as hotels,hospitals, or nursing homes, whichmeans our products are highly reliable.As a leading manufacturer of hot watersupply industry, we proudly introduce ourhigh efficient new Hot Water Heat Pumpsystem.Built-inInverter-drivenScroll CompressorHightemperature70ºCOver 4*COPOzoneFriendlyHot Water Heat Pump ensures an exceptionally high level of reliability by utilizing"Backup Function*".
