Compression heat pumps as an energy efficient devices

The aspect of energy efficiency is one of the most actual for Russia. Usage of thermal pumps allows to receive energy for functioning of buildings and constructions’ engineering systems. Questions of definition of thermal pumps efficiency indicators and allocation of ways for increasing their functioning are considered in this article. Operation of the vapor-compression thermal pump is carried out and the main indicators for energy saving are given. Literature about optimization of parameters of functioning thermal pumps is analysed. And as a result recommendations about an assessment of thermal pumps’ efficiency and about definition of terms of their payback are made.
