Refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature space and rejects it in a high-temperature space.
Refrigerant absorbs heat from the low-temperature space (evaporator)
Refrigerant is compressed to increase its temperature and pressure
High-temperature heat is rejected in the condenser
Refrigerant expands in the expansion valve to lower its temperature and pressure
Cycle repeats to
1 ton of refrigeration is the amount of heat absorbed by one ton of ice (2000 pounds) melting over a 24-hour period.
1 ton of refrigeration is equal to 12,000 BTUs per hour.
It is the amount of heat required to melt one ton of ice in a 24-hour period.
1 ton of refrigeration is commonly used as a unit of cooling capacity in the HVAC industry.
For example, a 2-ton air conditioner can remove 24,000 BTUs of heat per hour.
Static pressure is the pressure exerted by a fluid at rest.
Static pressure is the pressure exerted by a fluid that is not in motion.
It is the force per unit area applied in a direction perpendicular to the surface of an object.
Static pressure remains constant in a fluid at rest.
It is an important concept in fluid dynamics and is used in various engineering applications.
Example: Static pressure is measured in HVAC syste

The letters on a keyboard are placed in a specific layout called QWERTY, which was designed to prevent typewriter jams.
The QWERTY layout was developed by Christopher Sholes in 1873 for typewriters.
The layout was designed to separate commonly used letters to reduce the likelihood of jamming.
The arrangement of letters was based on the frequency of their use in the English language.
The QWERTY layout became popular and was
An air conditioner is a device that cools and dehumidifies the air in a room or building.
Air conditioners work by removing heat and moisture from the air.
They use a refrigeration cycle to cool the air.
Air conditioners can be used for both residential and commercial purposes.
They come in different types such as window units, split systems, and central air conditioning systems.
Air conditioners improve indoor air quality ...
