What are the applications of refrigeration?
Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, and air conditioning. Heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units.
What is domestic refrigeration?
[də′mes·tik ri′frij·ə‚rād·ər] (mechanical engineering) A refrigeration system for household use which typically has a compression machine designed for continuous automatic operation and for conservation of the charges of refrigerant and oil, and is usually motor-driven and air-cooled.
What are the types of refrigeration?
What Are the Different Types of Refrigeration Systems?
- Mechanical-Compression Refrigeration Systems. The most widely used refrigeration cycle method is mechanical compression.
- Absorption Refrigeration.
- Evaporative Cooling.
- Thermoelectric Refrigeration.
What is mechanical refrigeration?
: the abstraction of heat by means of a working substance subjected to refrigerating thermodynamic cycles in which the energy is supplied by a mechanical compressor : cooling produced by a machine instead of by melting ice.
What are the basic units of mechanical refrigeration system?
The diagram below illustrates the four basic components of every refrigeration system. These include the Evaporator, the Compressor, the Condenser, and a Metering Device. A refrigerant is then circulated through each component for the sole purpose of removing heat.
What is the basic principle of refrigeration?
The absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation are the main principles of the refrigeration process, or cycle.
Which cycle is used in refrigeration?
Refrigerators and heat pumps are essentially the same device; they only differ in their objectives. Reversing the Carnot cycle does reverse the directions of heat and work interactions. A refrigerator or heat pump that operates on the reversed Carnot cycle is called a Carnot refrigerator or a Carnot heat pump.
What are the four components of a refrigeration system?
A vapor-compression (or mechanical) refrigeration system has four main components – an evaporator, compressor, condenser, and metering device.
What are the three major refrigerant lines?
The suction line connects the evaporator to the compressor, the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device.
What are the major components of a refrigerator?
What are a refrigerator’s main components?
- Compressor. The compressor is the “heart” of a refrigerator.
- Condenser. The condenser sits on the back of a refrigerator, and is likely quite dusty.
- Evaporator.
- Capillary tube.
- Thermostat.
What is a refrigerant circuit?
The main components of a refrigerant circuit are therefore: The compressor has the function of circulating refrigerant inside the circuit, specifically drawing it in as a gas from the evaporator and then compressing it and delivering it at higher pressure to the condenser.
Is Freon a liquid or gas?
is a trade name for a class of chemicals (known as Chlorofluorocarbons or CFC’s) used as a refrigerant in air conditioning systems. Freon is a gas at room temperature and a liquid when cooled or compressed. Freon gas is colorless, non-flammable and relatively odorless. Some Freons have an ether-like odor.
How many Btus are in a ton?
12,000 BTU
How many KW is in a ton?
3.5169 kilowatts
How many BTUs is 2.5 tons?
30,000 BTU
How many BTUs do I need for 1000 square feet?
Size and Ceiling Height
| Area To Be Cooled (square feet) | Capacity Needed (BTUs per hour) |
|---|---|
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
How many BTUs do I need for 500 square feet?
11,500 BTU
How many BTUs is 4 tons?
A 4 ton air conditioner is one that can remove 48,000 BTUs of heat per hour from the house. For most people, though, 4 tons means 8000 pounds. (A BTU is a British Thermal Unit, approximately the amount of heat you get from burning one kitchen match all the way down.)
How many tons is 1500 square feet?
| ZONE 1 | ZONE 5 | |
|---|---|---|
| 1.5 Tons | 600 – 900 sf | 700 – 1100 sf |
| 2 Tons | 901 – 1200 sf | 1101 – 1400 sf |
| 2.5 Tons | 1201 – 1500 sf | 1401 – 1650 sf |
| 3 Tons | 1501 – 1800 sf | 1651 – 2100 sf |
How many BTU is 2400 square feet?
For example, if the bedroom and office area zone is 1,800 square feet and the living areas and kitchen are 2,400 square feet, add together the recommended BTUs for each. You’ll need between about 180,000 and 280,000 total BTUs for your home based on the climate and house factors considered in the calculator.
How many horsepower is 24000 Btu?
9.440 Horsepower
How do you convert BTU to HP?
To convert BTU per hour to horsepower use the following equation: Power (Horsepower) = Power (BTU per hour) x 2,545.
How many BTUs is 1hp aircon?
9,000 BTU
How do you find the horsepower of an air conditioner?
How to Calculate HP for an Air Conditioning Unit
- Multiply the air conditioner’s size in tons by 12,000 to convert its cooling capacity to British Thermal Units per hour.
- Divide this answer by 3.412 to convert it to watts: 18,000 / 3.412 = 5,275 watts.
- Divide the wattage by 745.7 to convert it to horsepower: 5,275 / 745.7 = about 7 horsepower.
How many kW is a 1hp aircon?
0.7457 kW
Is 1.5 HP aircon a size room?
Your aircon’s efficiency heavily depends on the space it will cool. Getting a bigger or smaller aircon is not necessarily better….TIP 1: Match your aircon horsepower (HP) to the size of your room.
| Room Size | Aircon Horsepower (HP) |
|---|---|
| 12 to 17 sq. m | 0.75 HP |
| 18 to 22 sq. m | 1.0 HP |
| 23 to 27 sq. m | 1.5 HP |
How many BTU do I need for a 12×12 room?
Calculated BTU: If you want to properly cool down a 300 square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have a tiny 12×12 room, for example. According to the US Department of Energy directive, an air conditioner’s most appropriate size would be 2,880 BTU unit.
