Greetings! I am looking to cool a computer room in the midwest where the temperatures can get below 0-degrees (F). What high effeciency mini-split would your recommend (would there need to be a heat strip for the compressor and/or a pressure switch for the condensor fan required?)?

Re: computer room cooling
I work on and like the sanyos.Yes there is usually a crankcase heater and fan cycling controls.As far as efficiencies.....thats up to what you wanna spend upfront or on electricity later on.Im in Ohio.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

It's likely the '33' you see displayed on your machine is the target temperature you've selected, as the fan speed goes from 1-10.
If you've selected 33 degrees as the target, your heater will only activate if the ambient room temperature drops below 33 degrees. It would then continue to run until the temperature reaches 33 degrees once again. The intelligent thermostat is engineered to heat the room to the desired temperature, then to run as needed to maintain this temperature.
If you want the heater function to run, try increasing the target temperature degree by degree until the machine comes on. But if you want to use the fan-only function in warmer weather, turn the target temperature down to 0. The LED indicator around the on/off switch will turn blue, and the machine will run in fan-only mode to cool you down with unheated airflow.

Air conditioners can only drop the temperature of the room temperature a maximum of 15 to 20 degrees F. A 95 degree F room temperature can drop to a maximum temperature of 75 to 80 degrees F. If the room temperature drops from 95 to 85 degrees F, Then the problem is having too small of a btu rating on the air conditioner or refrigerant has leaked out the sealed system which can affect the amount of cooling performance. You will have to buy a higher rated btu rated air conditioner if the temperature of the room drops by only 10 degrees F. Air conditioners are rated by how much heat that can be removed each hour. The more humid it is, the more work an air conditioner has to do. They cannot do more work than the btu rating that is listed on each air conditioner.
You might be feeling an increase in temperature coming out of the case in comparison to room temperature. I believe the problem you are experiencing is that computer is cooling itself down just from a higher temperature than you might expect hence the warm air. Download the program speedfan and check the temperature of your cores, they may be as high as 100 degrees farenheit, Don't worry about it too much unless you're actually overheating, if its a laptop make sure the bottom of the laptop isn't resting on anything solid as it severely reduces airflow in and out of the case making it heat up.
NEW UNITS HAVE A VISUAL ALARM PRE SET TO KICK ON AT 62 DEGREES OR ABOVE, WHE THE WINE COOLING UNIT READS 62 OR ABOVE IT WILL FLASH "AL" AND THE TEMPERATURE NUMBER THAT FORVED IT TO KICK ON, IT IS JUST A VISUAL ALARM IT WILL NOT TURN UNIT OFF OR STOP IT .
THIS FEATURE WILL SHUT OFF ONCE THE UNIT READS ANY TEMPERATURE BELOW 62 DEGREES.
The water expands up to more than 9% when it freeze below 0 degrees Celsius. Due to this phenomena, during the extreme cold weather when the ambient temperature falls below 0 degrees the cylinder blocks of the automotive engines often burst or crack badly.
This damage can be prevented by using the antifreeze coolant in the cooling system.
If the temperature is the problem this could be the solution
Problems with Temperature
If the refrigerator or freezer is not cooling properly, check temperature settings and air vents and ensure there is adequate room for proper airflow. Factory-recommended temperature settings are 0 degrees Fahrenheit (-18 degrees Celsius) for the refrigerator; and 37 degrees Fahrenheit (3 degrees Celsius) for the freezer.
If you need to adjust the temperature, do it one degree at a time and wait 24 hours before making additional adjustments. Check the air vents and make sure nothing is blocking them. Finally, if your refrigerator or freezer is too full, there will not be adequate room for air to circulate and cool properly. If these all check out, the problem could be with one or more compressor components and will require professional repair.

Within a few seconds the thermostat should make a soft click sound.
This sound usually indicates the thermostat is operating properly. If
the thermostat does not click, try the reset operation ( . If the
thermostat does not click after being reset contact your heating and
cooling service person or place of purchase for a replacement. If the
thermostat clicks, contact the AC manufacturer or a service person
to verify the cooling system is operating correctly. Or call the techline 18002842925.
An 11'500 btu Is appr. 1 ton of cooling capacity or enough to cool approximatly 450 sq ft of floor area. Be sure to read the instructions of course and be sure that all the packaging material was removed that may be restricting airflow. On high you should be able to easily feel the air blowing 10-15 ft from the unit and the air should be dropping about 15- 20 degrees when it exits the unit. So if the room temperature is 85 degrees the air exiting the unit should be around 65 -70. The amount of time it takes to cool the entire room depends on how big the room is and how much and the intensity of the heat infiltrating the room and the number and heat output of appliances and people in the room. Hope this helps you out GL!
