Eddie Wilcut and Elliot Fry, of the San Antonio Water System (SAWS), developed the spreadsheet, and then Kelly Lucas on our staff "webified" it. This calculation will not work for a whole house or commercial location, but is ideal for determining your mini split, through-the-wall, PTAC or window AC size. When we ran that EBN article, we also provided an online calculator to assist designers or building owners estimate how much air-conditioner condensate could be recovered. Wondering what size air conditioner you need Our BTU calculator is designed to determine how many BTUs are needed for a single room. A six-month payback was calculated on the condensate-recovery system at the Rivercenter Mall. Once selected click calculate and our air conditioning calculator will recommend the required size of air con unit in BTUs. The downtown Rivercenter Mall in San Antonio collects about 250 gallons of condensate per day, which is used to replenish the cooling tower losses, and the San Antonio Public Library collects about 1,400 gallons on condensate per day, which is used for irrigation. It makes so much sense there because of the large cooling load and high humidity. This is done by calculating your square footage. The city of San Antonio, Texas, has actively pursued this practice. To figure out what size air conditioner you require, you first need to determine the amount of BTUs you require. Instead of wasting it, more and more buildings, especially in parts of the country with hot, humid summers, are capturing that condensate for reuse. using a standing fan instead of the air conditioning when possible, putting on. Air conditioner (window unit) 1500-5000: Heater (home) 5000-20000: Heater (portable) 750-2000: Humidifier: 25-350: Dehumidifier. If you dont determine the proper size of the ductless system, you run the risk of your unit not effectively cooling or heating the space (or under or.
We'll use that information to help you find the right mini split system for your home.

Condensate drains carry away the water, usually into the sewer. Free electricity calculator to estimate electricity usage as well as cost based on the power requirements and usage of appliances. Results Tell Us About Your Home Fill out all of the fields provided to calculate your heating and cooling loads. Air blowing past the coils cools off as it goes by, and moisture from the air condenses on the coils. Here's an excerpt from that article on how that condensate is generated:Ĭooling systems rely on evaporator coils through which refrigerant fluid changes from liquid to vapor, cooling the coils in the process.

Our online calculator allows you to calculate how much condensate can be captured from an air conditioning system.īack in 2008 when I wrote a series of articles for Environmental Building News on water, one of those articles, Alternative Water Sources: Supply-Side Solutions for Green Buildings, examined various ways of harvesting water and included an in-depth look at collecting air conditioner condensate.
