Johnson Controls-Hitachi has introduced airCore, the first line of precision air conditioner (PAC) heat pump systems in the U.S. to use R-32 refrigerant. R-32 is a refrigerant with low global warming potential that produces fewer greenhouse gas emissions than R-410A. Low-GWP refrigerants such as R-32 reduce the impact of heating and cooling equipment on the environment and can meet upcoming refrigerant regulations.
Many states, such as California, have already established regulations that will phase out the use of high-GWP refrigerants in HVAC equipment, and the Environmental Protection Agency (EPA) has recently proposed regulations that allow only refrigerants with a GWP of 700 or lower to be used in new comfort cooling equipment starting January 1, 2025. By using low-GWP R-32, airCore units can comply with regulations before they go into effect. Cross Counterflow Heat Exchanger
In addition to using low-GWP refrigerant, the airCore line of universal outdoor units deliver energy efficient performance and make it possible for residential and light commercial applications, including small markets, restaurants, salons and medical offices, to decarbonize their heating and cooling when the electric units are powered by renewable electricity.
The airCore line features industry-leading piping lengths of up to 245 feet, which allows for greater installation flexibility and is especially advantageous for building configurations in coastal regions.
Plate Fin Heat Exchanger The airCore line comes standard with FrostWash, a self-cleaning technology that can improve indoor air quality. As dust, dirt and condensate collect on the heat exchanger, FrostWash freezes the moisture. It then melts and flushes the moisture and trapped contaminants away. Optional accessories, such as human sensor, Wi-Fi adaptor for airCloud Home, H-Link adaptor for airCloud Pro, third-party thermostat adaptor and low-ambient cooling kit for temperatures as low as -40 F.
