Mitsubishi Electric Y Series Hyper Heat Ductless Systems

Mitsubishi Electric has taken heating to a whole new level with our exclusive, patent-pending Hyper-Heat Inverter (H2iTM) technology. Even when outdoor temperatures drop to -25°C – a challenge for many competitive air-source heat pump systems – City Multi stays on the job, keeping the indoors at a comfortable and consistent level.

At the heart of the H2i technology is the Flash Injection Circuit. The Flash Injection Circuit consists of a Heat Interchanger (HIC) and a compressor equipped with an injection port. It works by allowing a portion of two-phase refrigerant (gas-liquid) to bypass the outdoor coil, and recollect heat energy at the Heat Interchanger (HIC) that is normally rejected during the flash process in the outdoor unit. The Flash Injection Circuit then injects the energized two-phase refrigerant at a lower temperature into the compressor through the injection port during the compression process. This reduces the temperature inside the compression chamber, allowing the compressor to run at higher speeds to offset the effect of low suction pressure and the low refrigerant mass flow rate due to low ambient temperatures. As a result, City Multi is able to maintain a high heating capacity and achieve higher performances without being affected by the cold.

The H2i system ensures a stable heating operation and constant comfort by delivering continuous heating for up to 250 minutes in one cycle and significantly reduces the defrost time between cycles.
The H2i system further enhances the heating operation of
City Multi. It pushes the boundaries of heat pump technology and is able to provide 75% of heating capacity at a COP of 1.7 in ambient temperatures as low as -13°F (-25°C).

Brian once again helped me with my project. Before I have installed a gas fireplace and this time I have installed an LG heat pump with 3 indoor heads. We had an amazing experience with Brian and his team for both projects from quote to installation. Brian is experienced, patient, reliable, and provides great friendly service. He’s also tells very interesting life stories which makes enhances the whole experience. All my future business is going to his company. Thanks again Brian!

Andrew Munn

Highly recommended. Brian at Cozy Comfort Plus supplied and installed 6 ductless heads on two compressors. The price was very competitive. The installation crew lead by Hamid did a perfect job. They explained the best locations for the equipment and answered all my questions. The work was completed a very short time after signing the contract. The team cleaned up the job site very carefully every night and were very careful indoorA.

We were looking to replace A/C, furnace and water heater and had a number of companies provide quotes. Brian of Cozy Comfort Plus was the most engaging person we met and most importantly, the person we trusted the most. His price was very competitive and we decided to go with him. His team of four men, led by Mir, came in and got the job done in one day. We are very happy with the Lennox equipment and the professional installation job done by Cozy Comfort Plus.
