HVACTA System Swap

by | Aug 26, 2024 | HVAC Program, HVAC Technical Academy, HVAC Technician

Loving HVACGetting all hands-on deck, today is system swap day. The past few weeks have led to this moment… success found (as well as cooling).

Books to the side, Time to Get It Done

Though there were a few struggles, clarity remained on focus from all. Provided are a couple photos of the first-time experience… I can’t wait to see what happens tomorrow!

Interested in a career in the HVAC industry, consider HVAC Technical Academy to help you get on the path quickly and effectively. Looking forward to hearing from you soon as enrollment is happening NOW for the October session.

HVAC Heat Pump: Talking About the Heat

HVAC Heat Pump: Talking About the Heat

by | Aug 5, 2024 | HVAC Program, HVAC Technical Academy, Universal 608 EPA

Reversing ValveWhen it comes to heat pump systems, now we’re talking about the heat. Straight cool systems are not equipped to reverse the flow of refrigerant to generate heat.

You had me with HEAT

In heating mode, the heat pump reverses the refrigeration cycle to extract heat from the outdoor air and transfer it indoors. The process begins with the outdoor coil acting as the evaporator, absorbing heat from the outdoor air despite cold temperatures. The refrigerant then travels to the indoor coil, now acting as the condenser, where it releases the absorbed heat to warm the indoor air. A blower fan circulates the heated air throughout the building.

Refrigerant Flow Reversal: Heat pumps are equipped with a reversing valve that switches the direction of refrigerant flow between heating and cooling modes. This valve allows the heat pump to provide both heating and cooling functions without the need for separate systems.

Want more? I thought so. Next time we will introduce Thermostat Control and the concept of Efficiency.

Straight Cool, More to Know

Straight Cool, More to Know

by | Jul 22, 2024 | HVAC Program, HVAC Technical Academy, Universal 608 EPA

Straight Cool TalkLet’s conclude our straight cool summary as many are ready to make the move.

Cycle Repeats and Thermostat Control

Cycle repeats: The refrigerant, now in a low-pressure, low-temperature state, returns to the compressor to start the cooling cycle again. This continuous cycle removes heat from the indoor air, maintaining a comfortable temperature inside the building

Thermostat Control: Like heat pump systems, straight cool systems are controlled by a thermostat. Users can set the desired indoor temperature, and the thermostat activates the system’s compressor and fan as needed to maintain that temperature.

What now: Straight cool systems are ideal for climates where cooling is the primary HVAC requirement. They are often more energy-efficient than heat pump systems during the cooling season since they don’t have the added energy demand of providing heating. However, in regions with significant heating needs, a separate heating system may be required alongside a straight cool system.

Overall, straight cool systems offer efficient and effective cooling solutions for indoor spaces, providing comfort during hot weather conditions.

Straight Cool, keeping you in the know

Straight Cool, keeping you in the know

by | Jul 3, 2024 | HVAC Program, HVAC Technical Academy, Universal 608 EPA

HVAC ALL the WayWe concluded our recent discussion with “causing refrigerant to condense into a high-pressure liquid…” let’s find out what happens next.

Expansion Valve and Evaporator Coil

The high-pressure liquid refrigerant then travels to the indoor unit (air handler), where it passes through an expansion valve or metering device. The expansion valve regulates the flow of refrigerant into the evaporator coil, causing a drop in pressure. As the refrigerant expands, it absorbs heat from the indoor air, cooling it down. The now-cooled indoor air is then circulated back into the living space by a blower fan.

Sounds pretty fundamental, and it is. Next time we will check out the cycle and thermostat control. Our concluding discussion will review Straight Cool efficiency.

Check back soon as there is much to come…

Wishing everyone a safe and fantastic Fourth of July!

Straight Cool, What’s Your Take?

Straight Cool, What’s Your Take?

by | Jun 27, 2024 | HVAC Program, HVAC Technical Academy, HVAC Training, Universal 608 EPA

What’s going on in the photo as Andrew guides students to determine if this condenser is a straight cool or a heat pump… what’s your take?

In a Cooling Process Nutshell

Straight cool systems operate on the principles of refrigeration. They use a compressor, condenser, expansion valve, and evaporator coil to transfer heat from the indoor air to the outdoors, thus cooling the indoor space.

Let’s break down a few concepts: The compressor pressurizes refrigerant gas, increasing its temperature. The hot refrigerant then flows to the condenser coil located in the outdoor unit. In the condenser coil, the refrigerant releases heat to the outside air, causing it to condense into a high-pressure liquid.

Check back soon as there is much to come…

Until then, write, comment, or email if you have any questions or would like a specific topic reviewed.

HVAC Vacuum Documentation

HVAC Vacuum Documentation

by | Apr 3, 2024 | HVAC Program, HVAC Technical Academy, HVAC Technician, HVAC Training

HVAC CareerEveryday we advance HVAC skills by DOING. Our aggressive hands-on approach places you in an advantage above all others.

During our 6-week workshops you will learn the proper strategies to pump down systems as we develop YOUR HVAC Clarity, Choice, Confidence, and Competence.

Vacuum Documentation

Documentation: It’s essential for technicians to document the vacuum pump down process, including evacuation times, vacuum levels achieved, and any relevant observations or notes. Proper documentation helps ensure accountability, quality assurance, and compliance with industry standards and regulations.

Overall, HVAC vacuum pump down is a critical procedure that ensures the proper functioning and longevity of HVAC systems by removing air and moisture contaminants. Following established protocols and best practices during the vacuum pump down process is essential for achieving optimal system performance and reliability.
