What are the difference between package unit and split unit?
A package unit contains all elements of the refrigeration cycle in one system. The 4 major components include: A compressor, condenser, metering device, and a evaporator. All elements are needed to complete the cycle of refrigeration. As for a split unit, All elements of the refrigeration cycle are used, however the condenser is located outside of the facility, while the evaporator is located inside of the facility. To better understand the difference in question, you must understand the job of each component in the refrigeration cycle. For example, a condenser is normally used to reject heat or cold air from a building, while a evaporator normally supplies heat or cold air to the building.
The thermodynamic law that explains the movement of heat energy during the refrigeration cycle is the?
second law of thermodynamics. This law states that heat naturally flows from regions of higher temperature to regions of lower temperature. In the refrigeration cycle, heat is extracted from the refrigerated space and transferred to the surrounding environment, causing the temperature inside the space to decrease.
without heat from the sun the water cycle would?
Without heat from the sun the water cycle would not work .
Which global cycle is most efficient in heat transferring?
Atmospheric cycle.
What is the ultimate source of the heat energy that causes the winds you feel?
The Heat Cycle

Why refrigeration cycle is called reverse carnot cycle?
The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.
What component allows heat pump to switch between heating and cooling modes of operation?
the reversing valve is what actually changes the refrigeration cycle from heat to cool. the reversing valve receives its signal from the thermostat.
Refrigeration can be described as?
Refrigeration is a process in which work is done to move heat. It was a closed-cycle that could operate continuously, as he described in his patent.
What is the net refrigeration effect in the refrigeration cycle?
The quantity of heat that each pound of refrigerant absorbs from the refrigerated space to produce useful cooling.
Difference between air refregeration cycle and reversed carnot cycle?
the Carnot cycle has 2 constant specific volume processes (heat in & heat out) the air refrigeration cycle is based on a brayton cycle which has two constant pressure processes.
How does an air conditioning unit remove heat?
To really understand how air conditioner removes heat? You have to know thermodynamics second law: " heat always flows from a material at a high temperature to a material at a low temperature." There're so much to it! AC condenser unit is the components that removes the heat in air conditioner. You also have to understand the other AC four basic components to know how and why it removes heat. Read: Basic refrigeration cycle and refrigeration cycle how air conditioner works refrigeration theory Youtube video on Principles of refrigeration video Good Lucks!
Explain the reverse carnot cycle and from them go to ac?
Carnot Cycle is an ideal thermodynamic cycle that describes the functioning of a perfect heat engine. In the refrigeration system we need a cooling effect. So, in effect, refrigeration cycle is reverse in process than that of a carnot cycle, and ofcourse not ideal. Air-conditioners also run on the similar cycle as refrigerators.
Bell Coleman Cycle it is the air refregeration cycle?
The Bell-Coleman Cycle is also known as the Air-Standard Refrigeration Cycle or Reverse Brayton Cycle. This 4-process refrigeration cycle involves isentropic compression, followed by isobarric heat rejection, then isentropic expansion (usually by a turboexpander), and finally isobarric heat intake.This cycle is commonly used in jet aircraft, using engine bleed air for compression and venting to the atmosphere. It is also commonly used in commercial air liquification plants.
Define flash gas and how it applies to the net refrigeration effects of the refrigeration cycle?
FLASH GAS - Instantaneous evaporation of some liquid refrigerant at the metering device due to pressure drop which cools the remaining liquid refrigerant to desired evaporation temperature.This flash gas cannot absorb any heat having a negative effect on the net refrigeration cycle

Does your ac need freon to run the heater in your home?
Only if you have a heat pump system which is basically an air conditioner which can run in reverse, absorbing heat from outdoors and discharging it indoors via the refrigeration cycle.
