Temp-Art was just retained to design and install a complete HVAC and fresh air system for a new three story Department store opening up this spring in midtown Manhattan.  The system will consist of VRV (Variable Refrigerant Volume) systems by LG Electronics.  We are excited about our new alliance with LG Electronics and the recent success stories we have written with their products on several installation

Ricardo Thank you for the comment and kind words about the comic.Regarding VRV smysets, I had dinner last night with Rick Frey, Senior Director of Hilton Engineering Support, and I learned more about this issue. The present Hilton standards call for the volume calculation to include the volume from the floor up to the height of the bed, only. Not the entire room volume. This severely limits the number of fan coils per condenser. Rick has been doing further research and has concluded that the refrigerant gas mix well enough that the entire volume should be the calculation basis. He indicated that up to 16 guestrooms can be served by a single condenser, typically. I have not confirmed this calculation, but this is good news for the hotel industry.

I simply wtnaed to thank you one more time for this amazing blog you have designed here. It's full of ideas for those who are really interested in this specific subject, especially this very post. You really are all amazingly sweet in addition to thoughtful of others in addition to the fact that reading your blog posts is a fantastic delight with me. And what generous present! Ben and I will certainly have fun making use of your ideas in what we must do in a few days. Our list is a mile long and simply put tips will be put to great use.

A forced air hniateg system is for hniateg only, and requires the addition of an outside compressor-condenser unit, and an evaporator [heat exchanger] coil inside in line with the forced air furnace.A heat pump on the other hand, is basically an air conditioner in which the "plumbing" is capable of reversing the flow of the refrigerant to cool a structure's interior during warm weather, and to heat it during cold weather.

Note that when there is a wide temperature differential, e.g., when heating a house on a very cold winter day, it takes more work to move the same amount of heat indoors as on a mild day. Ultimately, due to Carnot efficiency limits, the heat pump’s performance will approach 1.0 as the outdoor-to-indoor temperature difference increases. This typically occurs around −18 °C (0 °F) outdoor temperature. Also, as the heat pump takes heat out of the air, some moisture in the outdoor air may condense and possibly freeze on the outdoor heat exchanger. The system must periodically melt this ice. In other words, when it is extremely cold outside, it is simpler, and wears the machine less, to heat using an electric-resistance heater than to strain an air-coupled heat pump.

AFitz, thanks for the comment. I would get myself in trouble with alot of people if I said, “Nope! That’s all you need to know.”This article was written to put focus on more important things in a Central Energy Plant than just ‘how to control the chiller’. So, yes you need to know more about WHEN to enable and disable that chiller more than the HOW. Since as I wrote above… the HOW is easy. OFF.I am sure I will be posting up some articles and videos to help piece together the sequences of operation that tie together to make a Central Energy Plant (CEP) and chillers by extension… run.

Cheaper to buy a … Cheaper to buy a new unit. Much cheaper.It would need to have auxilary heat anyways unless it was grossly oversized to begin with. In which case it would make a poor air conditioner because it would not run long enough to pull out humidity. If you have the cash look into inverter driven heat pumps. Most mini splits and Nordyne builds a split system. If on a budget check out amana PTAC / PTHP. Get your window back and close the thing before you let all the air out.
