AIR PREPARATION SYSTEM FOR A GROUND HEAT EXCHANGER SIMULATOR
Abstract
In ventilation systems, ground heat exchangers are becoming more and more popular, which can be considered as a passive air-conditioning system. Two types of heat exchangers are used: with a membrane separating ventilation air from the ground and membrane-less. The air preparation system described below is designed to simulate the temperature change conditions corresponding to seasonal changes. It was proposed to use a heat transport system using Peltier modules. As a result, it was possible to reduce or increase the temperature of the air injected into the ground heat exchanger simulator. Using the computer simulation environment, the simulation of the work condition of an air preparation system was conducted. After the device model was built, functional tests were performed to determine its parameters. An analysis of the heat distribution on the system elements using a thermal imaging camera was also carried out. The obtained results of simulations and tests on the real object allowed to develop modifications increasing the functionality of the air preparation system to the ground heat exchanger simulator.
