Title: Data Acquisition System for a Ground Heat Exchanger Simulator
Abstract: As part of the search for effective ways of obtaining energy, a model of a ground heat exchanger was built. It is an element of the ventilation system of a residential building. In order to develop methods for designing ground heat exchangers, it was necessary to build a model to simulate the operation of such an exchanger in laboratory conditions. This article presents a data acquisition system dedicated to cooperate with a laboratory simulator of a ground heat exchanger. The data acquisition system uses a spatial grid of temperature sensors that allow obtaining information on the temperature distribution in the space of the simulator test chamber. The second set of measured parameters is the distribution of pressure drops along the porous bed filling the simulator test chamber. The data obtained from the sensors are registered in a system developed for the needs of the simulator with a one chip microcontroller with a Cortex core. The microprocessor system also performs simulator operation control functions. The design of the system provides the possibility of autonomous simulator operation with the simultaneous acquisition of measurement data that will be used to validate the simulation model used for computer simulation of ground heat exchanger operation.
