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.

HVAC Vacuum Pump Down: Evacuation and Monitoring

HVAC Vacuum Pump Down: Evacuation and Monitoring

by | Mar 29, 2024 | HVAC Program, HVAC Technical Academy, HVAC Training, Universal 608 EPA

HVAC Learning in ActionThe past few weeks have been exciting as our recent group of HVAC workshop participants have been installing systems, rebuilding, recovering, troubleshooting, and much more. With that, let’s get back to our vacuum pump down in detail.

Vacuum Evacuation and Monitoring

Evacuation: Once the system is prepared, technicians turn on the vacuum pump to start the evacuation process. The vacuum pump removes air and moisture from the system by creating a negative pressure environment, causing the trapped gases and moisture to be expelled through the pump’s exhaust.

Monitoring: Technicians monitor the vacuum level using vacuum gauges or digital vacuum meters throughout the evacuation process. The goal is to achieve and maintain a deep vacuum, typically below 500 microns, for a specified period. This ensures that the system is thoroughly evacuated, and the risk of moisture and air contamination is minimized..

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.

HVAC Vacuum Pump Down: Equipment and Preparation

by | Mar 11, 2024 | HVAC Program, HVAC Technical Academy, HVAC Training

HVAC career in SIX weeksWe’ve reviewed several topics as of late and now we will begin the journey of a key HVAC Service Technician requirement: Equipment and Preparation.

Vacuum Pump Down Equipment and Preparation

Equipment: HVAC technicians use a vacuum pump, also known as a vacuum pump down, to create a vacuum within the system. Vacuum pumps come in various sizes and capacities, and they are specifically designed for HVAC applications. Additionally, technicians use vacuum-rated hoses and manifold gauges to connect the vacuum pump to the HVAC system.

Preparation: Before starting the vacuum pump down process, technicians ensure all necessary connections are made and the system is properly prepared for evacuation. This includes attaching the vacuum pump to the system’s service ports, closing off valves to isolate the system, and ensuring that all components are sealed to prevent air ingress.

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.
