Chilled Water Air Handlers
Looking for some recommendations on Chilled Water Air Handlers. This will be for the cooling portion of our project only.
I had a friend do a Heat Loss Survey for me and I am doing a bit of research on what I will need for air handlers for the cooling side of this project. I have a chilled water unit already purchased since we need that for cooling our wine tanks. My plan is to utilize the same chilled water for air conditioning with chilled water air handlers and overhead ducting. (Exposed spiral ducting for the great rooms and conventional square ducting in the attic space above the smaller rooms.) The chiller has a 50 gallon chilled water reservoir built in to it so I am thinking it should be a fairly simple system to put together. I am looking for advice and a source for the air handler purchase.
Air Handler #1 will need to support 33,500 BTU's and Air Handler #2 26,900 BTU's. I am able to set the temperature of the chiller reservoir to what ever temperature I like depending on what is optimal for the AC system. (There is a month or so of the year where I will turn the chiller output temperature down to 10F to facilitate chilling wine below 32F but this will take place when the ac will not be cooling the people spaces and the radiant floor heat will be running.)
The air handlers will be located in an attic space and the ducting will split in to two runs with nearly equal cooling loads. Run #1 will be the fancy spiral ducting that will be exposed in a great room and run #2 will be conventional rectangular ducting hidden in attic space that will cool several smaller rooms.
Hopefully this is enough info.
