The compressor is the piece that keeps the refrigerant moving, as the low pressure is continuously pulled into the compressor to try and create some sort of equilibrium. The refrigerant enters as a superheated vapour at high pressure and temperature, it then passes along the tubes of the condenser. Essentially they all work the same way by passing a refrigerant between the main components of the compressor, condenser, expansion device and the evaporator to remove unwanted heat from … Would you believe that that heat is the heat that was in your home? It does this by changing the pressure and state of the refrigerant to absorb or release heat. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. […]. Thanks for sharing the informative post. These are the units that sit outside your home and have the large fan going round and round when it’s kicked on. And that, is the basics of hot refrigerants work in HVAC refrigeration systems. The chemical reacts by boiling through an endothermic reaction. For further information on this subject I would recommend visiting the Danfoss website. Once the refrigerant has been pressurized, the hot gas gets pumped into the condenser. The temperature of the room air is higher than the temperature of the cool refrigerant this allows it to absorb more energy and boil the refrigerant completely into a vapour. Today, we take refrigeration for granted, but once upon a time, fortunes were made shipping large blocks of ice around the world in insulated holds to sell to the rich. Evaporator control in industrial refrigeration engineering. The outside unit of an air conditioning system has metal fins all around the housing. An air conditioner has a refrigerant in it that cools the air as it cycles back into your home, allowing you to live more comfortably inside. A lot of information about Refrigerants and refrigerants work in all details Your site provides very useful information. The fans continue blowing, causing the now chilled air to be pushed into the house. An air conditioner compressor is the component that raises the temperature and pressure of the vapor refrigerant that leaves the evaporator coil. The temperature drops to a more manageable level, causing the piping to shift from burning hot to very warm. The refrigerant will leave the compressor and travel through the condenser at a temperature around 30 degrees higher than ambient outdoor air temperature. An example of a refrigerant would be water. This physical law states that heat absorption happens when a liquid turns to gas, which is exactly what a refrigerant does. Website by. The red valve will control how much goes into the unit and turned off when the correct amount as been added. These cookies will be stored in your browser only with your consent. This metering device is the computer that controls the situation and keeps track of how things are working. This further decreases the temperature. With a gas furnace you have the heat from the flame blowing into your home. Beckley, WV The compressor pushes the gas molecules together, heating them up as the pressure raises. Lets look at how refrigerant moves around the system. This is how it works: First, a compressor in your air conditioner compresses cold Freon gas. These common refrigerants all have extremely low boiling points compared to water. Spring is here, and among the other duties and tasks you need to perform for your home (such as spring cleaning and changing the batteries in the smoke alarms) comes the need to give your air conditioner a close look. Absorbing and Expelling Heat. It’s also one of the pieces to be most careful of, because the piping that leaves the compressor to continue on easily burns exposed flesh. Let us break it down for you. Some of the more common refrigerants on the market ate R22, R134A and R410A, although the laws and regulations on refrigerants are tightening and many of these will be phased out in the long run. The condenser has a few fans that blow across the pipes, cooling the gas. Refrigerant. When the refrigerant is pushed into the compressor, it is a low pressure gas. As the refrigerant gives up its heat it will condense into a liquid so by the time the refrigerant leaves the condenser it will be a completely saturated liquid, still at high pressure, but slightly cooler although it will have decreased in both enthalpy and entropy. One of the… This is very useful to know the working principle of refrigerant in the Air Conditioning Application. Expansion valve. These fins work like the radiator on a vehicle, and they help dissipate heat more quickly. As the name suggests, it “compresses” the refrigerant so that it turns from a gaseous state into a liquid state. This is also known as hidden heat. This consent is not required to purchase goods/services and you may always call us directly at 888-979-9579. The heat given off is what makes the condenser "hot to the touch." As the compressor pulls the refrigerant in, it rapidly compresses it, this forces the molecules together so the same amount of molecules fits into a smaller volume. Back again, the refrigerant, now a warm low pressure gas, is pumped into the compressor, where it repeats the process over and over again. The condenser is where all the unwanted heat is rejected out into the atmosphere. Great post. The motor rotates the male rotor through the crankshaft. Scott Zimmerman – Interview for Nuclear Energy Insider, Valley College Announces 5-Year Grant of Accreditation with ACCSC, Upcoming Events for Alumni to Attend and/or Participate In. The refrigerant leaves the evaporator as a low temperature, low pressure vapour. This compressor uses helical screw rotors to compress larger volumes of refrigerant. Nothing could be further from the truth. We also use third-party cookies that help us analyze and understand how you use this website. A small amount of oil is combined with the Freon gas to lubricate the compressor. The screw compressor competes with lar… This working fluid exits the compressor as a high-pressure, hot gas, and it moves to the condenser. Take The Free Quiz. While the pump is working the blue valve will be opened to let the pump work. The compression involves the motor and the male and female rotors.
