A Static Mathematical Model for Cascades of Heatpump Installation of Multipurpose Thermal Point

[摘要] In the article the static mathematical model of work of heatpumping part of multifunction thermal point on the basis of the cascade thermal pump is described. Thermal point provides the consumer with heat energy for heating and hot water supply, refrigerating energy for conditioning. Also the complex can provide the consumer with both types of energy (seasonally) for ensuring ventilation of the building. The main advantages of thermal point is high coefficient of performance in all range of work of installation, and also in high utilization coefficient of primary fuel. The coefficient of performance remains high due to optimization of heatpumping cycle - in selection of certain temperatures for each mode. Increase in utilization coefficient of primary fuel is reached by utilization of waste warmth from sewer drains, exhaust air of the ventilation unit, and also useful use of heat and refrigerating energy as heating/conditioning implementation coproducts.
