Markus Benzenhofer, from TWA Systems, came to the job site today and reviewed the Wine Cellar. Markus is working on the design and layout of the cooling panels in the ceiling, which will use our waste cold water to cool our wine.
Reviewing the Wine Cellar Mock Up
To design the cooling system, Markus needs to understand the load on the system. The load on the cooling system is a function of many elements, including the size of the panels, the distance from the panels to other surfaces, and the temperature, volume and velocity of water going through the panels.
Importantly, Markus also reviewed how the cooling panels would be supported and where the attachments to the chilled water manifold would be. Markus wanted to ensure that the design was robust and would support maintenance and allow access to the various components.
With the mock up of the wine racks in place, Markus reviewed the distance from the exterior walls to the panels as well as the distances from the wine racks to the panels. He asked about attachments and described the load of the panels, which would need to be attached to the ceiling.
In order to understand the impact of the lighting, Markus and Bryan held the sample panel in place (using a ladder and measuring tape) and then tried to see what it would look like. It was difficult to do with any precision.
After taking some notes, Markus commented, ‘A precise scale drawing would help to analyze the issues with certainly. A mock up would be perfect.’
Markus left and Bryan set to work with Al and Nep, putting a mock up of the dropped ceiling and cooling system together.
Our 24 ft sliding glass door in the closed position. Note there are only two vertical lines resulting from the three sliding glass panels. Also, note how the vertical lines do not interrupt the 36-inch wide hardwood flooring and how the panels are different sizes.
The sliding glass panels are now behind the feature concrete wall in the Dining Room. A clear 24 ft span!

Measuring the distance to the hollow core concrete panels. The ceiling will be dropped so we can insulate the Wine Cellar. As well, the cooling panels will be attached to the dropped ceiling structure.
After Markus left, Bryan worked with Al and Nep to put a fast mock up of the ceiling structure with cooling panels in place.

View of front of ceiling, with actual distance from panel to soffit. The Redwood in the bottom and side of soffit are mocked up with scrap material so we could see the angles. Note the attachment to the dropped ceiling is not mocked up correctly although the height of the panel is correct.

Reclaimed Redwood that Al and Nep have cut for the racks in the Wine Cellar. This wood is old growth, clear heart Redwood. Al deconstructed a deck in a previous project and saved the wood to be used in the future. It will look spectacular in our Wine Cellar!
