The DL GEOTHERM has been designed as a miniaturized ground source heat pump air conditioning system to study the cooling and heating processes of the reversible heat pump plant with water-to-water heat exchangers.
This training device allows students to study in detail the working principle and thermal cycle process of the ground source heat pump and learn about the system characteristics and control methods. It covers several topics such as hydraulics, mechanics, and thermodynamics and control.
Its working principle is based on the Carnot cycle, using groundwater or surface water.
A compressor system, consuming a small amount of electricity, is used to continuously take out a large amount of low-grade heat energy from the water and convert it into a small amount of high-grade heat energy for indoor heating.
In summer, the cooling water system of the unit runs in reverse to take out the residual heat in the room and release it to the ground or water to cool down the air conditioner. In addition, energy can be stored in summer and released in winter.
