Bringing Year-round Comfort Solutions to Extreme Climates
The cooling and heating success of Mitsubishi Electric’s INVERTER heat pump systems is well documented. Our Hyper-Heating INVERTER (H2i) P-Series technology advances the process a step further with the added benefit of year-round comfort with a single system even on the coldest days of the year in most areas. The 2.5- and 3-ton wall-mounted, ceiling-suspended, ceilingcassette and ducted indoor units connected to the H2i P-Series outdoor units are flexible enough to satisfy almost any light commercial or institutional renovation or new construction project.
The Next Generation in Heat Pump Technology
These H2i P-Series outdoor units give a new level of performance to Mitsubishi P-Series models, providing the extra heat-generating power it takes to deliver comfort and consistency in extreme climates. H2i units use Mitsubishi Electric’s INVERTER-driven scroll compressor technology to achieve the desired room temperature quickly, maintaining it consistently while simultaneously conserving energy. Plus with the integration of our exclusive H2i flash technology, these H2i P-Series units recover heat energy that is normally wasted in the flash process at the outdoor coil. This process helps the H2i system overcome issues commonly associated with conventional heat pumps such as decreases in low-side pressure, refrigerant mass flow rate and operational capacity. As a result, H2i P-Series units exhibit 100 percent of rated heating capacity at 5° F and 80 percent at -13° F outdoor ambient temperatures (see Figure 1). Plus they use R410A environmentally friendly refrigerant.

H2i P-Series heat pumps offer a variety of features designed to take the worry out of temperature control such as automatic restart in the case of power outages and automatic cool/heat changeover. And its long line length capabilities of up to 260 ft. expand application possibilities.

Sometimes cooling spaces such as computer or mechanical rooms and kitchens is necessary even when the temperature is below freezing. Air conditioning down to 0° F outdoor ambient temperature is possible with the addition of a wind baffle. Whether cooling or heating, the H2i P-Series gives you the flexibility to temper extreme outdoor temperatures.

Warm Air Quickly!
At startup, a special circuit in H2i P-Series quickly delivers refrigerant to the air-conditioning cycle, which rapidly increases the mass flow rate in the system. As a result, air at comfortable temperatures begins flowing from indoor units right away. Even at an outdoor temperature of -13° F, the H2i P-Series system can discharge 100° F temperature air from the indoor units. At 5° F outdoor temperature and above, the discharge temperature reaches an impressive 110° F with a 40° F temperature rise (Indoor Unit Discharge Temperature). This feature translates into a comfortable climate in all zones of a home or office, whether cooling or heating, no matter the temperature outside.

Two in One
If you have a large space such as a long room or hallway which would be considered one zone, two indoor units can be connected to one outdoor unit to cool or heat the space, providing the maximum amount of comfort. The process, in which two indoor units act as one to spread the outdoor unit’s capacity over a large area, is called Twinning.
