NIPPON PMAC Co., Ltd. List of Products and Services

PMAC is an air conditioning unit that can provide heating and cooling individually using water as a heat source. It can be used for heating and cooling over a wide water temperature range (7 to 45°C). It can share cooling water and heat sources for server cooling, so there is no need to worry about outdoor unit placement. In winter, it is also possible to utilize the server's exhaust heat for heating offices and other spaces (water temperature 5°C or higher). In this case, the PMAC unit helps reduce the cooling load on the heat source unit. The PMAC unit has a structure where the indoor and outdoor units are integrated, which means the amount of refrigerant used in the refrigerant circuit is smaller compared to EHP and similar systems. Additionally, since the refrigerant circuit is contained within the unit, there is no need for refrigerant work or additional charging, making it easy to install. <Features> ● Heating and cooling possible with server cooling water ● No need for outdoor unit placement due to shared heat source ● Possible use of server exhaust heat for heating ● Reduced refrigerant usage ● Easy installation *For more details, please download the PDF or feel free to contact us.

By expanding the low-temperature range of the source water temperature, it effectively utilizes renewable energy (such as groundwater and geothermal energy) and unused energy (waste heat from factories, hospitals, hotels, etc.) as a heat source for heating and cooling. It is now possible to operate with source water at low temperatures (below 15°C), improving the energy consumption efficiency for cooling. In buildings with long cooling periods, the energy consumption efficiency for cooling at partial loads is further enhanced, resulting in significant energy-saving effects. 【Features】 ■ Expanded low-temperature range for source water ■ Compatible with renewable and unused energy ■ Improved cooling energy consumption efficiency ■ Added small-capacity unit (0.5 horsepower type) suitable for small room air conditioning loads ■ Operating temperature range for source water Cooling: 7°C to 45°C / Heating: 5°C to 45°C *For more details, please refer to the PDF materials or feel free to contact us.

The "PMAC System" is an individual air conditioning system that uses small heat pump units distributed throughout, with water as the heat source. The heat source water piping is a two-pipe system (supply and return), allowing for stable automatic heating and cooling operation unaffected by weather conditions. Additionally, the heat rejection (latent heat) at the cooling tower helps mitigate urban heat island effects. When both cooling and heating loads coexist within a building, heat recovery between units can effectively utilize heat and promote energy savings. 【Features】 ■ Detailed response through an individual air conditioning system ■ Energy-efficient air conditioning system ■ Stable air conditioning unaffected by weather conditions ■ Space-saving and reduced construction work ■ Long lifespan with manufacturer maintenance *For more details, please refer to the PDF materials or feel free to contact us.

The heat pump fan coil unit "PAFMAC" is a cooling and heating free air conditioning system suitable for hotel guest rooms and hospital rooms using a two-pipe chilled and hot water system. With high-efficiency air conditioning utilizing an inverter compressor and DC fan motor, it enables the replacement of existing two-pipe system fan coil units, achieving cooling and heating freedom and increased capacity. The number of units adopted can be selected according to the needs of the hotel, whether fully converted to PAFMAC or partially adopted based on the grade of guest rooms. Additionally, since the existing water piping can be used as is, installation is easy. This minimizes the need to take guest rooms out of service. 【Features】 ■ An individual air conditioning system that enables automatic cooling and heating year-round with a two-pipe chilled and hot water system. ■ Replacement is possible from just one room (mixing with existing fan coil units is also possible). ■ Significant reduction in room temperature complaints. ■ Operating modes adjusted according to the seasons. *For more details, please refer to the PDF document or feel free to contact us.
