The aim of the work was thermodynamic analysis of the theoretical model of heat pump ventilation and air conditioning system with recirculation of cold depending on the outside air parameters to maintain temperature and humidity conditions in the production area during the warm season. Using the numerical analysis with the method of successive approximations air parameters at nodal points of the model were determined and its energy efficiency was estimated. These data made it possible to estimate operating modes of the system depending on outside air parameters, characteristics of ventilation and air conditioning objects and heat entrances to an area. The importance of cold energy recirculation to ensure high efficiency of the heat pump system was quantified. The studied system may be suitable for use in countries with temperate continental and humid tropical climates in the entire range of ambient temperatures, when the object of ventilation is a production area with a low air exchange rate.
