EFFICIENCY OF HEAT PUMP AND ADSORPTION SYSTEM OF CONSERVATION OF ENERGY EQUIPMENT

Abstract

The paper presents the development of heat pump and adsorption system conservation metal equipment. This system is intended for air drying which is used for long-term conservation of power equipment on the plant station. The processes corrosion of metal details are slowed down when the relative humidity is less than 40%, so this system is designed to provide deep air dehumidification at low electricity costs. A theoretical model of this system is developed in the article and presented calculation of this system. A mathematical model for numerical study of the system operation is developed. The numerical analysis of thermodynamic efficiency was performed, the change of the air mixture parameters at the main points of the system was investigated, the influence of the change of temperature and the relative humidity of the surrounding air on the system operation was analyzed and shows some conclusions. The limits of real-world usage of this system are also analyzed and presented where can be used this system and her benefits. The results obtained show that the application of this system allows to significantly reduce the specific consumption of electric energy for drying the working air compared to the base system without the use of a heat pump for any values of the ambient air parameters. This conclusion presented that use heat pump decrease energy consumption without deterioration of the process of air dehumidification. The graphical dependences of the system performance on a wide range of operating temperatures and humidity of the outside air were obtained. Also, graphical dependences of the heat pump energy conversion factor and air parameters at the main points of the system over a wide range of operating air parameters are presented and analyzed.
