Questions:
1. How do I go about starting this project to get exact sizes for everything. I cant have any mistakes because we ony have one shot. Very little money. Especially with the large gap of temperatures I can choose to run the refrigerant on. I am use to exact calculations.
2. I would like to finnish this with exact calcuations for condenser sizing and evaporator with the pump. I am very confused how to go about on these calculations.
3. Any help with be benefitial because we are doing this t help save peoples lives and buy land to help natives and aid in building a native hospital and be a centre for endangered species. Also create a school we need some presitge to help the poor children.
Thank you so very much this is my first project and I have never done calculations for this in my life.
