1. Objective
To understand air conditioning process and able to determine the energy and mass balances of the process.
2. Introduction
Air conditioning, which may be described as the control of the atmosphere so that a desired temperature, humidity, distribution and movement are achieved, is a rapidly expanding activity throughout the world. Other than providing human comfort, there are numerous application of air conditioning including computer laboratories, pharmaceutical industries, inspection and storage of sensitive equipment, horticulture, animal husbandry, food storage, and etc.
Generally, the air conditioning unit draws air from the environment into the duct. The air flows through the humidifier, and then the evaporator of the refrigeration plant where it is cooled and dehumidified under certain conditions. The water supply to the water heater is assumed to be at a temperature of 25oC. Whereas, the fan used in this air conditioning unit has the power output of approximately 72 W at normal operating conditions.
