MEC3110 Climate Control

Advanced · 1 credit · TMT - Trades, Manufacturing and Transportation

Description: Students expand their knowledge of the purpose, operation and servicing of standard heating and air conditioning systems.
Prerequisite: MEC2030: Lubrication & Cooling
Parameters: Access to air conditioning test equipment and related resources. Note: Work must be supervised and checked by a certified technician when student is working with refrigerants.

Outcomes The student will:

1 demonstrate established safety and care procedures when working with climate control systems
- 1.1 demonstrate knowledge of and follow laboratory safety procedures
- 1.2 generate a list of safety concerns when working with refrigerants
- 1.3 outline the legal restrictions about the disposal and recycling of R12 refrigerants
- 1.4 identify the safety and environmental concerns with R12 and R12 replacements
2 identify the purpose and describe the functions of heater and air conditioning system components
- 2.1 describe the operation of a heater; e.g., heat exchange, the operation of controls for fan speed, air flow controls
- 2.2 identify components of an air conditioning system
- 2.3 describe refrigeration principles
- 2.4 describe air conditioning system operation
3 perform inspection, diagnosis, service and repair procedures on heater and air conditioning systems
- 3.1 identify the causes and repair procedures for standard heater operation malfunctions; e.g., blocked or leaking heater core, temperature cable adjustment, fan motor noise, vibration, speed abnormalities
- 3.2 show how to conduct a visual and tactile check of the operation of the refrigerant system and assess the service needs
- 3.3 identify the cause of malfunction in a climate control system and repair, as required, after consulting with the vehicle owner/teacher
- 3.4 pressure test the air conditioning refrigerant system and confirm the normalcy of system operation by comparing data with the service manual
- 3.5 on the air conditioning system, perform a leak test, evacuate system, recharge, then perform leak test again
4 identify global concerns about the release of refrigerants into the atmosphere as well as the alternatives to standard refrigerants, and identify the required recycling procedures
- 4.1 research the effect of refrigerants on the ecosystem
- 4.2 research alternate refrigerants
