React Energy designs and installs geothermal systems for residential and commercial applications. Vertical heat exchange loop, horizontal loop, and closed lake loop are used for commercial and institutional applications. The vertical heat exchange loop installed by the company is a closed loop heat exchanger.
Geoexchange systems are designed to provide heat during winter and cooling during summer. With the help of the refrigerant, the system transfers heat from the higher temperature area to a lower temperature area. The heat exchanger incorporated with the geoexchange systems is designed to transfer heat during summer and extract heat during winter. The vertical heat exchange loop contains high density polyethylene piping in different lengths. It can be installed in vertical boreholes with a depth up to 120m. If the soil has low thermal conductivity, it may require more pipes.
The vertical heat exchange loop contains fluids inside the pipe. Fluids are pushed out through a heat exchanger placed within the geothermal heat pump. Installing the vertical heat exchange loop system is more expensive than the horizontal borehole heat exchanger. Once the ground loop heat exchanger is installed, it begins to operate efficiently. The polyethylene pipes used for this loop system will not corrode, degrade or break down.
