Abstract:

The use of heat pumps (HP) is currently one of the most promising areas in the energy sector. Today there are many heat pumping stations (HPS) in heating systems with heat pumps working together.
The article solves the problem of optimal load distribution of HP, working together to minimize consumption of electric power for various methods of description of transform coefficients. It is found that the uniform distribution of heat loads minimizes consumption of electric power to a value higher than the optimum for thousandths of a percent for the ideal (in the theoretical analysis) and real HP. Thus, to minimize power consumption necessary for the evaporators of HP, working together were connected in parallel, and condensers - sequentially. In practice it is sufficient to control of the uniformity of the heat load of the same type HP as their further optimization may be ineffective if only because of a lack of precision measuring instruments.
