Hvac Refrigeration Cycle
- Thermodynamic heat pump cycles or refrigeration cycles are the models for heat pumps and refrigerators.
The complete cycle of stages (evaporation and condensation) of refrigeration or of the refrigerant.
The complete circulation of refrigerant through an air conditioning system as it changes temperature and pressure, i.e., changes its state from vapor to liquid, then back to vapor.
- Heating, Ventilation and Air Conditioning.
- The general industry term encompassing a variety of home comfort equipment, including air conditioners, furnaces, thermostats, filters, ductwork and filters.
- The term used to refer to the mechanical systems which heat, cool, filter or dehumidify air in a room or building. An example of an alternative HVAC system would be Ground Source Heat. For more information on Ground Source Heat click here.
System Diagnostics and Troubleshooting Procedures
This module provides the reader with the necessary information to successfully diagnose air conditioning and refrigeration system problems. Systematic troubleshooting and diagnostics of; airflow problems, refrigerant cycle malfunctions, suction and liquid line restrictions, oil logged evaporator, undercharge, overcharge, compressor inefficiencies, dirty condenser, air in the system, restricted metering device, and low and high condenser entering air temperatures are detailed.
Systematic diagnosis of the above listed problems using service checklists to assist the service technician to quickly and efficiently troubleshoot a system is explained.
Basic and advanced leak detection covering the following six classes of leaks are detailed;
pressure dependant leaks
temperature dependant leaks
vibration dependant leaks
combination dependant leaks
cumulative micro leaks
Testing procedures for evaporator leaks, condenser leaks, suction and liquid line leaks are all thoroughly explained. Advanced leak detection and modern leak detectors are also included and explained in detail.
System evacuation, deep vacuums, micron gauges and scales, vacuum pumps, vacuum manifolds, system pressure drops, vacuum breaker valves, and gas ballasts are all explained as well as illustrated.
System cleanout procedure after a compressor burnout using suction and liquid line filters and associated graphs are included. Combination acid and moisture test kits are also a part of this module.
The completed HVAC and Pump
Man, even the guy who replaced my HVAC coil said the condensation pump was a monster. I would say it was trying to polish a turd with another turd. But at least I have cold air in the summer and heat in the winter.
