HVAC
This term refers to the quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
What is a BTU
These detailed drawings show the vertical interior of a building as if it were cut in half.
What are Section Drawings
This device is used to change AC voltage from one level to another
What is a Transformer
This valve is designed to allow water to flow in only one direction, preventing "Backflow" in a system.
What is a Check Valve?
This unit provides both heating and cooling in one "package," commonly found on on top of commercial buildings across Winnipeg.
What is an RTU
This term describes the resistance to airflow within ductwork, which is a critical factor when selecting a blower or fan.
What is Static Pressure
These are the final set of drawings submitted after construction is complete, reflecting every change made in the field.
What are As-Builts
This color (wire jacket) is reserved for the "Grounding" or "in a standard electrical circuit.
What is Green
this technical term describes water that has been treated to meet Manitoba's "Office of Drinking Water" standards and is safe for human consumption.
What is potable water
This HVAC system uses a "Reversed" refrigeration cycle to extract heat from the outdoor air to provide energy-efficient heating in non extreme climates.
What is a Heat Pump
This unit of cooling capacity is equivalent to the removal of 12,000 BTUs per hour
What is a Ton of cooling
This specific tool in Inventor allows a designer to create a 3D part from a 2D sketch by "pushing" the shape into the third dimension.
What is the Extrude command?
This is the standard frequency of the AC power grid in Canada and the United States
What is 60 Hz
This "U" or "S" shaped pipe section under a sink holds a small amount of water to prevent sewer gases from entering the building.
What is a P-Trap
This psychrometric term refers to the temperature at which water vapor in the air begins to condense into liquid.
What is the Dew Point
This is the most common refrigerant currently being phased out in Canada in favor of lower-GWP alternatives.
What is R-410A
This type of view, common in mechanical design, "pulls apart" a complex assembly (like a pump or valve) to show how the individual pieces fit together.
What is an Exploded View
This protective device "trips" to disconnect power when it detects an overload; it is essentially a modern, resettable fuse.
What is a Circuit Breaker
this specific "pipe-joining" method which uses a mechanical press tool rather than solder or torches to increase safety and speed
What is ProPress (or Press-fit)?
These units use a refrigerant coil and a fan but no ductwork, making them popular for retrofitting server rooms or offices.
What is a Mini-Split
In a standard DX cooling cycle, this component is responsible for releasing heat from the refrigerant into the outside air.
What is the Condenser
This tool allows you to perform "Stress Analysis" on a part to see where it might deform or break under a specific load.
What is Finite Element Analysis
This protective device is specifically designed to open a circuit when it detects a small leakage of current to the ground, often required in wet areas.
What is a GFCI (ground fault circuit interrupter)
This phenomenon occurs when water is shut off abruptly, causing a pressure surge that can reach up to 10 times the normal operating pressure
What is Water Hammer
This is the temperature of the air as measured by a standard thermometer, ignoring the effects of moisture.
