![]() The process air is cooled and dehumidified in the absorber. As the evaporator temperature is increased from 7.2☌ of conventional air conditioner to 15☌, the COP of HACS increases by 35%. The capacity of the ammonia compressor selected is 42.5 kW with an evaporator temperature of 15☌ and condenser temperature of 50☌. ![]() This paper presents the simulation results of a HACS, working with ammonia refrigerant and calcium chloride LD. temperature for human comfort, while reducing the electrical energy requirement compared to a vapour-compression system alone. These systems have the ability to provide the required humidity and. ![]() The HACS has received considerable attention due to its inherent ability to use low-grade thermal energy and reduce the latent cooling load. The combination of a vapour-compression system and a liquid desiccant (LD) system is the hybrid air-conditioning system (HACS) which can be energy efficient and environmental friendly. Incorporation of the above mentioned control systems have resulted in almost 23% saving in energy. The results were displayed using VISIDAQ software, which enables real time process data to be automatically displayed on screen. In order to study and compare various parameters like condenser, evaporator and indoor air temperatures, motor speed and power consumption an Analog to Digital converter (ADC) card was used to interface the different sensors with a computer. A triac based speed control system for blower motor and a Microcontroller based ON/OFF control system for replacing the conventional thermostat. This paper is aimed at conserving energy by modifying the conventional window air conditioner by incorporating two automatic control systems. Thus, even under conditions of high temperature and high humidity, discomfort can often be greatly reduced by increasing the airflow. Increased air speed over the body and clothing surfaces can increase convective and evaporative losses. Human comfort is influenced by physiological factors determined by the rate of heat generation within the body and the rate of heat dissipation to the environment. ![]() Load Calculation and Applied PsychometricsĢ0.Concern for the environment and increasing price of energy requires, reviewing conventional practices and developing novel alternatives for conserving energy, in a window air conditioner.
