Active Energy Systems
Active Energy Systems’ IHEX’s innovation is its ability to freeze water without the latter sticking to the freezing surface, achieved through surface chemistry. At a customer-product level, the IHEX acts as the evaporator of an ice-making chiller. This chiller, the first of its kind, will be able to take in liquid water and return an ice-slurry. When connected to a water storage tank, this chiller acts as the “charging engine” of a thermal energy storage system, producing ice to later be used as a cooling source. The storage tank communicates with the thermal load, the commercial building, through a secondary heat exchanger. The IHEX directly utilizes refrigerant to improve energy efficiency and reduce the need for a heavy-duty compressor.
