3 IR-TO-WTER This series of extremely efficient air-to-water heat pumps incorporates numerous original air conditioning technologies developed by Mitsubishi Electric. The eco-friendly units offer the perfect combination of powerful heating and cooling performance and economical running cost. The Secret Behind Our Stellar Heat Pump Efficiency is Capturing the Heat that is lready in the ir. Heat pump systems are now capturing attention as a decisive catalyst in efforts to conserve energy. With this technology, atmospheric heat is harnessed; that is, it is collected from the air and used as a heat source to provide highly efficient heating. For example, a heat pump with a coefficient of performance () of 4.0 uses of electrical energy input and 3 of heat energy transferred from outside-air to the heat pump for an impressive final heat output of 4. compressed to raise the temperature Produces 4 times the amount of energy input ir-to-water Heat Pump Principle (when heating) Electrical Energy Input and Heat Circulation < Case of 4.0 > Heat absorbed from the air 3 Evaporator Water heat exchanger Heat 3 Heat bsorbed from the ir Expansion valve expands refrigerant to lower the temperature Hot water outlet 4 4 Heat Output Drastic Reductions in Operation Cost and CO2 Emissions No Sacrifice in Comfort Heat pumps differ from conventional heat sources in their ability to effectively use atmospheric heat. unit with a of 4.0 has a heat output of 4 for each kilowatt of electricity consumed.

4 Improved Performance Mitsubishi Electric s unique Flash Injection Circuit is a key component in the high heating performance of the ZUBDN. This technology enables the rated heating capacity to exceed that of the power inverter series by 30%, even when operating with sub-zero temperatures outdoors, and the guaranteed operating range of the heating mode is extended to -25 C. Thanks to ZUBDN technologies, ir-to-water heat pumps can now be used to heat homes in cold regions too. capacity () 5 0 pprox. 30% improvement over same-sized ZUBDN without injection (5HP model) PUHZ-HW40VH/YH PUHZ-HW2YH 5HP model Without injection 4HP model Without injection -25 o C Guaranteed heating operation range is extended to -25 C ambient temperature -20 o C - o C Power INV 3HP Power INV 4&5HP ZUBDN 3-5HP -25 C -20 C -5 C -7 C -2 C 0 C Outdoor-air intake (wet bulb thermometer) *bove date shows only ir-to-water usage -25 o C -20 o C -5 o C -0 o C -5 o C 0 o C Mitsubishi Electric s Flash Injection Technology The Key to High Performance at Low Outdoor Temperatures Flash Injection Circuit ZUBDN Injection compressor (injection port) Flash Injection Circuit Indoor HEX Power receiver B Outdoor HEX Heat Interchanger (HIC) LEV B LEV flow LEV C Flash Injection Circuit Heat interchanger (HIC) B Injection Compressor The Mr. Slim model of the ZUBDN Series is equipped with Mitsubishi Electric s original Flash Injection Circuit, which is comprised of a bypass circuit and heat interchanger (HIC). The HIC transforms rerouted liquid refrigerant into a gas-liquid state to lower compression load. This process ensures excellent heating performance even when the outdoor temperature drops very low. In traditional units, when the outdoor temperature is low, the volume of refrigerant circulating in the compressor decreases due to the drop in refrigerant pressure and protection from overheating due to high compression, thereby reducing heating capacity. The Flash Injection Circuit injects refrigerant to maintain the refrigerant circulation volume and compressor operation load, thereby maintaining heating capacity. Mollier Chart Image Representing Flash Injection Circuit Operation LEV LEV B LEV C Heat Interchanger (HIC) B Injection Compressor HIC cross-sectional view passes through LEV C (refrigerant pressure lowered) doesn t pass through LEV C Purpose: Transform liquid refrigerant into liquid-gas state Effect: Injection circuit increases energy efficiency The compressor is subjected to a heavy load when compressing liquid refrigerant, and the result is lower operation efficiency. The addition of HIC supports refrigerant heat exchange at two different pressure levels. The heat-exchange process transforms the injected liquid refrigerant into a gas liquid state, thereby decreasing the load on the compressor during the compression process. flow Purpose: To increase the volume of refrigerant being circulated Effect: Injection port Discharge port Suction port Normal refrigerant flow Improves heating capacity at low outdoor temperatures, and enables higher water outlet temperature adjustment and higher defrost operation speed passes from the HIC into the compressor through the injection port. Having two refrigerant inlets makes it possible to raise the volume of refrigerant being circulated when the outdoor temperature is low and at the start of heating operation. 30
