We ask members to Donate what they could to help Make Hive13 a COOL place this Summer. You stepped up, and the air conditioning is installed.
The contractor installed two 5 ton 13 seer condensing units on 1st floor roof
These are the largest units that the furnaces can handle.
We closed Elevator #4 to keep the cool inside.
Otherwise the cool air will drop straight down the elevator shaft to the basement.
The 2701 building owners have agreed to replace the roll up door with a modern version that we can power and attach to our RFID system. Meanwhile elevator #4 has been down for repair of damage that came when rainwater backed up in the basement. The elevator door replacement is going slow, but it will happen. Until then #5 elevator still works.
What we have learned about the AC
It was advised that 10 tons is enough to reduce humidity and hold temperatures in the high 70’s
So far, so good, but we can do better
The Hive13 space does not have much sun load compared to most buildings
The building has a lot of thermal mass. Wall temp averaged ~ 80F last summer
We were warned that the ductwork could become covered in condensation
Condensation is happening - Solution – Insulation on the duct out to the first vent register
We have recycled mylar bubble food delivery bags to wrap the ducts this week
The Contractor found the outside condensers were covered with cottonwood lint
We need to put condenser cleaning on our schedule for next spring
Hosing off with a garden hose should be sufficient
The Contractor recommends MERV 8 filters and warns that higher MERV filters reduce efficiency
MERV 8 filters are now installed
The Contractor recommended that we close off the space with a wall along the back
The wall will allow us to stop losing our cool and lower the humidity
Exhaust fans for wood dust, hot crafts, welding, laser ... blow cool air out and suck in hot humid air
Wherever appropriate we should recycle the air through dust filter boxes
