Professional Refrigeration and Ac Technician Course in Rawalpindi Pakistan

The course consists of different refrigeration cycles and understanding of psychrometry and psychrometric processes used for the purpose of air-conditioning.Further, the comfort air-conditioning and indoor environment health are also addressed in this course.Refrigeration and Air Conditioning Mechanics install, maintain and service residential, commercial, industrial and institutional heating, ventilation, air conditioning and refrigeration units and systems. They also connect to air delivery systems, install and service hydronic and secondary refrigerant systems and associated controls. Their duties include laying out reference points for installation, assembling and installing components, installing wiring to connect components to an electric power supply and calibrating related controls. They also measure, cut, bend, thread and connect pipe to functional components and utilities. They maintain and service systems by inspecting and testing components, brazing and soldering parts to repair defective joints, adjusting and replacing worn or defective components and reassembling repaired components and systems. As part of service and commissioning, refrigeration and air conditioning mechanics start-up, test, charge, adjust, calibrate, balance, measure, verify, maintain and document systems.This course is an examination of automotive heating, ventilation, and air conditioning systems, with a focus on identification of malfunctioning parts and the repair of these systems. Students will diagnose the heating and air conditioning system and determine necessary action for unusual operating noises and inoperative conditions. Students will diagnose temperature control problems and failures in the electrical controls of heating, ventilation, and air conditioning systems and determine necessary action. we discuss some of the common basic elements of HVAC systems and the types of systems that are used to meet the requirements of different building types and economic considerations. Since HVAC is used to maintain not only an acceptable level of thermal comfort within a space but also a healthy environment, the conditions that provide a comfortable and healthful indoor environment for humans are introduced. They are addressed by physiological considerations, environmental indices, and control of indoor air quality. The design of an HVAC system is dependent on a good estimate of the heat gain or loss in a space to be conditioned. The next step is the determination of heat transmission in building structures and solar radiation, including overall heat transfer coefficients, climate, solar angles, and solar irradiation. Then the maximum probable heat loss (space heating load) in winter and heat gain (space cooling load) in summer are determined in order to size the HVAC system. Several computational methods, such as transfer function method and conjugate heat transfer method, are presented. Following the selection of the HVAC system, it is often desirable to estimate the quantity of energy necessary to heat and cool the building under typical weather conditions and internal heat sources. The methods cover from simple degree-day and bin methods to advanced computer analysis.
