▪ HiCoolac's Water Source/Ground Source Heat Pump Unit uses water source modular technology, the host exchanges heat through high-efficiency heat exchanger and intermediate medium circulating water. ▪ Replacing the original outdoor unit air-cooled heat exchange.Combining water source heat pump technology, modular control technology and R410A environmental protection refrigerants, it combines the technical advantages of air-cooled modular air-conditioning and water-cooled chillers.Thus, it is possible to utilize the heat energy of low-grade heat sources such as oceans, soils, industrial waste heat, and municipal sewage for cooling/heating, which greatly saves energy.
