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

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.

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.
