ACR 001 Principles of Refrigeration & Air Conditioning I (48 clock hours)
The course covers the fundamental principles of refrigeration and air conditioning. What is the compression refrigeration cycle, explaining in detail the function and location within the system of each of its fundamental components. The diverse types of compressors, condensers, evaporators, metering devices and accessories used in refrigeration and air conditioning are also studied. The technical services to be performed in an installation are explained and the types of refrigerants are mentioned, their characteristics and their safe handling.
ACR 002 Refrigeration and Air Conditioning Application II (48 clock hours)
This course studies the residential and commercial air conditioning systems and begins with an analysis of what is the air conditions and comfort, the properties of the air and its treatment in the cooler. Topics related to the typical working temperatures of an air conditioner are included and a detailed study is made of the different air conditioning systems, such as; central and local air conditioners including split systems (splits), mini split, compact systems, heat pumps water chillers (chillers) and window air as well as its efficiency, advantages and disadvantages of each of them.
EST 100 Introduction to Electricity (48 clock hours)
This course is an introduction to the fundamental principles of electricity and magnetism. These topics cover the concepts and basic laws related to the matter and the electronic structure of the atom, electric current, electromotive force, electrical resistance, Ohm's Law, fundamental parts of a circuit, direct and alternating current, single-phase and three-phase current, magnetism and electromagnetism, inductance, capacitance, electric power. In addition, serial, parallel and mixed connections of resistive, inductive, capacitive and composite electrical circuits are taught, as well as the characteristics of each one. Other subjects dealt with are the inductors, where a study is made of the relays, transformers and electric motors, explaining the types that exist, the characteristics, principles of operation and application of each of them.
ACR 101 Applied Electricity to Refrigeration & Air Conditioning I (48 clock hours)
The first part of this course will cover electrical system of residential air conditioning and heating equipment. The second is the theoretical part it is divided into several parts: The first section covers in detail the traditional single-phase electric motors used in compressors, fans, condensing unit and its components.
ACR 102 Applied Electricity to Refrigeration & Air Conditioning II (48 clock hours)
The third part covers the control circuit and its components. The fourth part covers the air handler and its components. Each section covers topics related to the operation principle, the function, the location and the connection of each of these components within the system. You will learn to interpret electrical diagrams and plans related to these circuits, as well as to use electrical codes.
ACR 420 Principles of Thermodynamics (48 clock hours)
The course offers in a straightforward way the basic principles of thermodynamics closely related to refrigeration, such as: internal energy, heat, work, temperature, pressure, volume, weight, specific gravity, mass density, volumetric flow and the different states matter, with its phase changes. This course also will cover, what is called enthalpy and entropy is mentioned and the laws of thermodynamics and the laws of gases are covered in a simple and effortless way. The different thermodynamic processes and their characteristics are described.
