Yes we do.

Rectangular ducts are necessary whenever you’ve got a tight space that won’t allow for the height of round ducts. These square ducts also fix the issue of the ugly connection between fan coil and main duct. Takes up less height Easily connects fan coil to main duct Better for low pressure systems

Commercial refrigeration systems in the US are mostly rated in tons of refrigeration and this term is used widely in other parts of the world. However, outside the US, cooling systems may be normally specified in kW (or MW) or in Btu/h. The roots for refrigeration are in the ice making industry, and the ice manufacturers wanted an easy way of understanding the size of a refrigeration system in terms of the production of ice. If 288,000 Btu are required to make one ton of ice, divide this by 24 hours to get 12,000 Btu/h required to make one ton of ice in one day. This is the requirement for the phase change from liquid to solid — to convert water at 0°C (+32°F) into ice at 0°C (+32°F). As a practical matter, additional refrigeration is required to take water at room temperature and turn it into ice.

Smelly air, basically, some of which is recycled in order to reduce the size of the compressor plant. On ships this is 70% recirculated, 30% fresh, meaning the compressor set only needs to be 70% of the actual cooling capacity. Another byproduct of air con systems is water. This is evidenced by the pool under your car on hot days, the drips from your window type air con, and the gallons discharged by ships’ and shopping malls’ air con plant. I believe our local mall here uses this water in the rest rooms toilet flush, which is a good idea.

“Ventilation” has a specific definition in the US Submarine Service. It means replacing old internal air with fresh outside air. When a submerged submarine “ventilates” it sticks a snorkel mast (a big vertical hollow tube) out of the water, sucks fresh air inside, and blows old air out into the water through another hollow tube.

In the 1930’s most apartment buildings were heated with a steam heating system. Steam was preferred over a hot water system with an electric circulator pump because pumps were expensive and prone to failure. And there might not have been any electricity in the building when it was originally built. (This was especially true (if you could find a pump at all) when steam systems were first introduced in the mid 1800’s.) But distribution of steam was easy. You basically just created steam, and it flew through the pipes to where ever you wanted it to go. So steam was preferred for large apartment buildings.

The limit switch will open periodically to prevent over heating. A fault will appear when it's open or if it doesn't reset within a specified period of time during which the blower is expected to circulate enough air to cool the heat exchanger to below the set point. After that period the control will lock out and possibly try for ignition again later if the limit resets in the meantime. In modern furnaces an open limit switch will always bring on the main blower as a safety feature when there is a call for heat but it is not the blower control which usually operates on a timer built in to the control module.

That is like asking how high is up, you left out, where you live, the kind of system and whether or not this is new construction or remodel/ replacement. All of these things have direct bearing on cost.

Most often, there really is no difference. Luxury homes are rarely branded “luxury” from the things people can’t see or do not care about. For ventilation, you might go for separate thermal control of individual rooms, but we’d be beyond luxury before you’d see it anywhere. Usually you just set a standard temperature and top off the heat (if necessary) with the local heating system. Water will be the same - the only difference between “standard” and “luxury” homes would be the number of outlets and the tap itself. Shower units might be very fancy, with local pressure regulation, electronic temperature control, fancy lights and thelike. But that’s about it.

Heating, Ventilating, and Air Conditioning (HVAC) perform heating and cooling for residential, commercial or industrial buildings. The HVAC system may also be responsible for providing fresh outdoor air to dilute interior airborne contaminants such as odors from occupants, volatile organic compounds (VOC’s) emitted from interior furnishings, chemicals used for cleaning, etc. A properly designed system will provide a comfortable indoor environment year round when properly maintained.An air conditioner cools and dehumidifies the air as is passes over a cold coil surface. The indoor coil is an air-to-liquid heat exchanger with rows of tubes that pass the liquid through the coil.

Your home’s central heating system is amazing. It’s an interesting process that involves water moving through the many parts of the system to generate heat. It starts with natural gas entering your home from a pipe. All the heat required to generate warmth is stored inside the gas. This gas goes to the boiler which burns it to make heat energy from the gas. This heat energy is transferred to the water. What follows is the heat being moved and pushed through the system using an electric pump. Inside each radiator is a closed loop through which the water flows. The water enters at one side and leaves the other. The water is cooler as it leaves the radiator than when it enters because the radiator gives off heat. Once the water has passed through all the radiators, the water will have been cooled down to a considerable level and it then needs to return to the boiler to pick up greater amounts of heat.
