For design condition of 32 C and 55% RH outside in the summer, how much electricity does your air conditioner pull at this condition if it has a COP of 2.1 at this condition? In this case, assume two people are home adding 120W each and an additional 2.4 kW of internal loads. 90 W/ft of solar radiation is hitting the roof at noon when the sun is directly overhead (the design condition). Don't forget about latent loads. How does each of these change with a 70% effective energy recovery ventilator (simple plate heat exchanger)? a. Winter sensible load at design conditions b. Summer sensible load at design conditions c. Summer latent load at design conditions
