The system design of window air conditioner does not evolve in one day. Due to the continous efforts are taken by the refrigeration and air conditionging professionals, successful and economic models of window air conditioners are currently used. This paper states about the development of window air conditioner with phase change material and water as refrigerants. Developed air conditioner was ...

There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this ar...

Reduction of energy consumption and rise of cooling is a major concern in the air conditioning system especially in the area with very hot weather conditions. In hot weather conditions, the air conditioner takes more electrical power consumption to bring the comfort in specified area. In many Middle East countries, the atmospheric temperature approaches 40°C to 50°C or sometimes higher. During ...

Continuous innovations and modernization has greatly contributed to the development in automobile industry. Automobile has become a huge luxury for everyone in all the countries. All modern automobiles like cars are equipped with air conditioner and heater units. An air conditioner alters the properties of air (temperature and humidity) to more comfortable conditions in building, house or autom...

The integration of large-scale renewable energy poses great challenges for the operation of power system because of its increased frequency fluctuations. More load frequency control (LFC) resources are demanded in order to maintain a stable system with more renewable energy injected. Unlike the costly LFC resources on generation side, the thermostatically controlled loads (TCLs) on the demand s...

This review paper presents the work of various researches on the performance of capillary tube ,used in air conditioners with various refrigerants. Research carried out by different authors uses different type of capillary tubes (straight, twisted, coiled) in different length and diameter. they determined various parameters like coefficient of performance (COP),cooling capacity, energy efficien...
