Just got an email at work that they are misting the a/c unit to a switch gear room. Sounds like a temporary thing for high heat until a new unit can be installed.
my unit is on the east side of the house with a lot of tall trees, so doesn't see the heat of the day
Shading a condenser at best adds 1% efficiency but normally lowers efficiency significantly by restricting air flow which in turn heats up the immediate ambient air temperature. The negative impacts are usually seen after a homeowner plants shrubs around the unit or places a shade structure over the condenser’s upward oriented exhaust. A 3 ton condenser is moving 170,000 cubic feet of air per hour so the ambient air temperature is the biggest factor.
i read about not planting shrubbery to try to shade it, and a shade structure might be to close, although a 'sailshade' might work if high enough
Of course you still have observe the other needs for siting the unit. We once had a place on the Jersey shore. The neighbor tried to block the passage between the houses by installing the AC unit right next ours.
strategic. we once looked at a house, and there was a horrible noise in the backyard behind the fence. when i took a peek, it was the neighbors pool pump, who had placed it as far away from his home as possible.
Here is a example of the product line that my son and I engineer and do the load calculations , sell and install From beginning to Turnkey deliver full system package. This particular system that you see in front of you is 126 tons of heating and cooling heat recovery system. There are three individual systems here that are grouped in pairs of three so it’s a triple redundant system. Each individual cabinet attaches to a single line set that are bonded together to form one large system. Each unit is 14 tons of cooling X 3 = 42 tons. X three systems. 42X 3= 126 tons. The indoor air handler configuration is 1.3 times the outdoor condenser rating. 163 tons of indoor Air handler’s capacity. There are several thousand feet of copper piping. A few hundred braised joints. Thousands of feet of High voltage Three phase high current wiring times thousands of feet of control Signal wiring. Comparing this to the Prius Prime on a level of complexity. The Prius prime would be considered nothing more than your water cooler that you have the 5 gallon upside down bottle attached to. Something that a child with a fifth grade education can repair. As for a cost in comparison for the materials list on this job and the labor. A Prius prime with all the options would be roughly the price of a Starbucks latte. This type of system here you would never even allow a HVAC technician who works on normal residential split air conditioning to even touch the system to let alone think that he would be allowed to diagnose it and add refrigerant. Give you example somebody on one of my old past systems allowed a regular refrigeration technician think that he was going to add refrigerant to it and destroyed $150,000 system and cost the customer in loss product development and shut down time roughly 1/ quarter million dollars because of a simple little mistake. Last year I was at a job site to look at a system that was improperly installed on a hotel. The failure from leaks was costing the hotel $30,000 a month to keep the system recharged and working well they look for a solution to get it fixed because of incompetence from a senior contractor that was in the business for 30 years but he attempted to install one of the systems for his first time. The losses to the hotel will be nearly $3 million to repair and the contractor is bankrupt. So when I compare this to automotive air-conditioning or fixing a Prius and thinking about $1000-$3000 somebody is quoted for a repair by a dealership that is like purchasing a can of beer from the corner mom and pop store. Just the cost of this one single system cost more than a few homes depending what state you live in.
Lol, buy a 1962 Frigidaire it would stil be working today. I was curious and wanted to get one to but heard some models had problems.
