The air cooled condensing unit includes the compressor, condenser, and fans and is installed outside on the roof or on a slab beside the building. I feel forced to decide what maladies I would prefer for myself and my cats, ie. Fortunately, there are a number of reliable methods available to evaluate antifreeze quality. It does not perform as well in colder temperatures, unlike Ethylene Glycol. At certain concentrations the solutions may be cloudy but dispersible above the cloud point; they should clear with. Therefore, intoxication with ethylene glycol should not be misdiagnosed as lactic acidosis in patients with metabolic acidosis and elevated lactate levels.
