How do you measure Sub-Cooling for a R-22 AC system
SUB-COOLING IS THE THE "HEAT BELOW SATURATION". THE SUB-COOLING LEAVING THE CONDENSER IS CALCULATED BY TAKING THE (ACTUAL)CONDENSING TEMPERATURE AND THEN SUBTRACTING (MINUS)THE LIQUID REFRIGERANT TEMPERATURE (USE THE CHART)LEAVING THE CONDENSER.=THE SUBCOOLING.
NORMAL SUBCOOLING AT THE CONDENSER OUTLET SHOULD BE 10*F.
THIS WILL ENSURE THAT LIQUID WILL NOT FLASH INTO VAPOR BEFORE IT GETS TO THE
EXPANSION VALVE, SHOULD THERE BE A SLIGHT INCREASE IN TEMPERATURE OR A SLIGHT DECREASE IN PRESSURE DUE TO A PRESSURE DROP.
SUB COOLING INCREASES CAPACITY & PREVENTS FLASH GAS IN THE LIQUID LINE AHEAD OF THE EXPANSION VALVE.
I HOPE THIS IS VERY CLEAR, AND HELPS U FIGURE OUT HOW TO MEASURE IT.

An AC 45TS would typically be hotter than an AC 44TS. This is because the AC unit's cooling capacity is measured in BTUs, and a higher BTU rating denotes a more powerful cooling capability.
An open short circuit on an AC compressor refers to a failure where the electrical circuit is interrupted, preventing the compressor from receiving power. This can occur due to issues like a broken wire, a blown fuse, or a malfunctioning relay, leading to the compressor not operating at all. As a result, the cooling system may fail to function, causing inadequate or no cooling in the space being conditioned. Identifying and repairing the open circuit is essential for restoring proper AC operation.
Should be about 120 VAC.
Possibly a plugged (internally or externally) radiator. your A/C condensor is located in front of your radiator, and generates alot of heat of its own, when you turn on the A/C, your putting that heat directly through the cooling system. the radiator and coolant cant circulate fast enough to cool properly. when you turn off the A/C, incomming air flow cools just enough to bring your water temp down.
The meter should be on the AC scale. In Canada and US the reading should be 240 on the outside blade holes and 120 volt from the outside blade holes to the center blade hole. The U shaped pin is the ground. No voltage from it to the center pin.
A 12000btu AC is considered 1 ton of cooling. 18000btu is 1.5 tons. One ton of AC will give you the cooling you would get by melting one ton of ice. EPM
Cooling fan not working, or your cooling system needs a complete service. The cooling fan should be on continuously when the A/C is on.
An AC 45TS would typically be hotter than an AC 44TS. This is because the AC unit's cooling capacity is measured in BTUs, and a higher BTU rating denotes a more powerful cooling capability.
Some people prefer to have the windows open and the AC on, while others prefer to keep the windows closed and rely solely on the AC for cooling.
The purpose of the AC drain pipe in a cooling system is to remove excess moisture that accumulates during the cooling process, preventing water from leaking or causing damage to the system.
The purpose of the AC condenser pipe in a cooling system is to release heat from the refrigerant gas, allowing it to condense into a liquid form, which helps in cooling down the air inside the vehicle.
AC misting systems can be effective in cooling outdoor spaces during hot weather by lowering the temperature through the process of evaporative cooling.

A window AC unit is typically easier to install and more affordable, but may be less efficient and have lower cooling capacity compared to a wall AC unit. Wall AC units are usually more efficient and have higher cooling capacity, but they are more complex to install and generally more expensive.
Using a portable AC duct for cooling a room offers benefits such as easy installation, flexibility to move the unit around, and cost-effectiveness compared to traditional AC systems.
Is it possible that it was steam and not smoke? If the AC freezes up, it will stop cooling until it thaws. Then, it will being to operate again.
