According to the spec sheet for the coil:
2gpm, 200cfm and water/air temperature difference of 70* should be about 4,760Btu/hr.
Given that the water heater is 1440W at a claimed efficiency of 98%, I am expecting it to be able to handle about 4800Btu. I have no idea if this will turn out to be...
Awesome, thank you. So the total pressure drop will be pressure drop will be the drop across a 8" - 6" reducer and short pieces of round duct, plus (If I read the Titus document correctly) somewhere between 0.07 - 0.13" WC across the box with damper full open, plus between 0.04 - 0.15" WC...
"I am building an HVAC system model (see other post)." Your response reads "WOW! If you don't know what you are doing, don't build a model at home with your own money to learn!" Thanks for the assistance but man why did you need to package it in a vitriol sandwich.
BTW I will be using a JACE...
My assumption is that the power leads are attached to the commutator and so are electrically insulated form the windings. This would also suggest insulation test cannot be performed using these leads.
I applied power to the pump for just two seconds to hear the impeller spin and it did appear...
I am building an HVAC system model (see other post) and chose a Bell and Gossett Ecocirc+ 20-18 pump. I got this pump open box on ebay and there is a short return window so I decided to check motor windings resistance upon receipt.
I am used to measuring windings on larger three-phase and...
Thank you for the references to Valve authority and PICV. Terms I am not familiar with that I will go and research.
The vendor was just trying to provide a solution that matches the specifications in the provided schedules. All parties did want to offer the solution resulting in the lowest...
1) Still finding this hard to understand. I always thought the pressure drop at the outlet of the coil was related to the resistance against flow inside a given coil. Given inlet pressure remains the same, but outlet pressure is decreased to a lower value, that would indicate lower flow due to...
I have located the answer to question #3 at the following location (Titus website):

I see you have resolved the situation but wanted to contribute...
In situations like this I found it useful to start by taking surface temperatures of problem surfaces, sometimes with the help of an infrared camera for efficiency, then using a Fluke 971 or similar to check dew point of...
I am in the process of building a miniature air handler/VAV/Boiler system at home. The purpose of this system is for more deeply learning Hydronics, controls, fan/VAV controller interactions, PI(D) loops etc and it is not designed to be efficient, simple, or reasonable for real life application...
