ENERGY ANALYSIS OF A HEAT PUMP AIR HANDLING UNIT FOR THE DEHUMIDIFICATION AND AIR CONDITIONING OF A PRODUCTION PREMISE

The article presents the results of thermodynamic analysis of the theoretical model of the heat pump system of ventilation, air conditioning and dehumidification of the production room with variable values of internal moisture and heat generation during the transition and warm seasons. The influence of exhaust air energy recovery on the system efficiency is established and evaluated. As a prototype was adopted blacksmith shop, where it is necessary to maintain technological conditions (temperature and relative humidity). Calculations were performed using the method of successive approximations to estimate the air parameters at the nodal points of the system. This established the theoretical refrigeration efficiency of this system and showed the benefits of energy recovery to reduce energy consumption for the system. This model can be used for the design of air handling units with a set heat pump circuit.
