Air Conditioning and Heat Pumps
This is a five-day class that can be presented as a complete package or taken in one or two day module increments.
Air Conditioning and Heat Pump I
Day One: Theory
In this session, we focus on heat transfer, the relationship between temperature and pressure and an introduction to the refrigeration cycle. The purpose of this class is to develop an understanding of thermal dynamics. This class creates the foundation needed to develop an understanding of the Refrigeration Cycle.
Air Conditioning and Heat Pump II
Day Two: Refridgeration Cycle
In this class, the students will develop an understanding of the different components in the cycle and how they interact with each other. The students will learn what the refrigeration does in each component and how the conditions inside the house and outside have an affect on the component and the refrigeration inside. We will also spend time understanding what super heat and sub cooling is all about and the importance of being able to take these measurements. The overall objective of these first two days of training is to get the students to learn and understand the refrigeration cycle.
Air Conditioning and Heat Pump III
Day Three: Procedures
In this session, we focus on procedures and techniques for refrigeration recovery, evacuation and charging both air conditioners and heat pumps. There will be review of the refrigeration cycle and time spent on further understanding the importance of measuring super heat and sub cooling. We will also talk about service procedures, such as leak detection and brazing.
Air Conditioning and Heat Pump IV
Day Four: Troubleshooting
In this class, we focus on troubleshooting and servicing residential and light commercial air conditioners and heat pumps. We begin with a brief review of the refrigeration cycle and then perform some troubleshooting problems. We will then cover proper service techniques regarding component replacement, driers, contamination, piping and equipment replacement. Our goal in this class is to get the students to see how all of the components work as a system and to be able to use symptoms to help diagnose problems. The students will learn what it takes to be accurate and effective troubleshooters.
Air Conditioning and Heat Pump V
Day Five: Controls
This class is designed to focus on the electrical side of the system. The students will have a brief review of some basic electricity and we will spend the day understanding the controls related to air conditioners and heat pumps. Transformers, relays and contactors, defrost boards, pressure and temperature switches, all of these controls and more will be reviewed and talked about. There will be opportunity for the students to receive hands on experience during this class on our training boards using some of the mentioned controls. Before attending class, the students should have attended a Basic Electricity Class, either ours or someone else's. We can incorporate a Basic Electricity class into this format (Controls I). It would then be the fifth day of training and the Controls class would be the sixth.
Controls I, Theory
This is a one-day class intended for people both new to the field and experienced. This class is the first module of a two-module class. Each module being one day. In this session, the focus is on the fundamentals of electricity and how it relates to the HVAC controls. The students will be introduced to proper meter use and understanding the measurements. We will also spend time making and reading wiring diagrams. There is demonstration and opportunities for the student to get hands on experience throughout the class. Our goal in this class is to simplify the function of controls and their purpose.
Controls II, Service and Application
This class is the second of the two-module Controls class. In this session, the focus will be on service and application of controls. We will begin with a brief review of the basic circuit using different controls. Voltage and Amperage ratings on controls will be discussed. There will be time spent on the use of meters and troubleshooting controls. This will be done through discussion, demonstration and hands on activities. Wiring diagrams will be used during activities to help the students apply what was reviewed throughout the class.
