Contributions to Modeling and Simulation of Thermal Processes Specific for Greenhouses Heated with Geothermal Energy

Large part of the greenhouse annual energy requirements are for heating purposes, thus having significant influence to the production operational cost. Use of geothermal energy can be an economical solution for their decreasing, however utilization of such source has own specifics in comparison with conventional ones. They can be turned in favor for the concrete use when applied and used in a right way. The paper presents some characteristic problems connected to utilization of low-temperature geothermal waters for heating greenhouses.
