Hello, I'm wondering if anyone can help me out by providing their interpretation of the ASHRAE requirement for minimum ventilation for a building consisting of several hundred storage lockers, which are accessed from interior corridors (just like what you'd see on "Storage Wars"). The locker...
Hello, I'm trying to resolve what I read as the NBCC requirements, and what I keep seeing done in practice for new high-rise buildings with respect to stair and elevator shaft pressurization systems. I am in the midst of designing the HVAC systems for a new 10-storey apartment, and want to be...
Hello,
I'm working on a design for a multi-storey apartment building. Each suite's kitchen will have a residential-style range hood over the stove-top, each one containing a washable grease filter, and the hood will recirculate the air back into the kitchen. ASHRAE requires that each kitchen...
I will typically specify a dielectric union to be installed whenever dissimilar metals are joined. When copper and steel pipe are joined, the steel pipe will corrode due to the galvanic action. But, when stainless steel is joined to copper (in a domestic water system) will a dielectric union...
Hello all. I'm working on the HVAC design for a resort, which has a service/storage area in the basement under the suites of one wing of the building. The basement takes up only half of the footprint of this wing, with the other half of the wing on a slab-on-grade. There is to be a walk-in...
Can anyone tell me what an appropriate ventilation rate would be for a small room (3'x8'x10'h) used to store two liquid chlorine storage tanks? The pool consultant's drawings indicate that ventilation is required (with no CFM or ACH rate given), with duct inlet at low level. Would this ductwork...
Here in Canada, the new Building Code prohibits providing ventilation air to apartments via pressurizing the corridor, and transferring into the suites. We now find it preferable to introduce ventilation air directly to the suite's fan coil, to meet the outdoor air requirements. The suites in...
According to the National Building Code of Canada, the practice of exhausting air from occupied spaces into a parking garage is normally prohibited, due to the risk of air flowing back from the garage into the occupied areas. However, in the explanatory section of the code, it indicates that the...
Hello,
When entering data into HAP, we usually first do a take-off from the drawing, using Excel to keep track of the properties of each space. Entering the data from Excel into HAP is often very time-consuming, if there are many spaces.
Looking through the files in the HAP program directory...
I'm trying to find a piece of HVAC equipment that can provide DX cooling, and heating via gas or electricity. The application is for an apartment/hotel suite, with a ducted supply and return air system, sized for about 500 - 1000 CFM. It would basically be a typical hotel room PTAC, but with gas...
