What is difference between refrigeration and air conditioner?
Air conditioners have circulation systems designed to project cool air away from the units while refrigeration units have circulation systems designed to retain coolant in a confined space. Refrigeration systems circulate cool liquids and gases through a series of tubes and vents.
Is air conditioning a form of refrigeration?
An air-cooled system is a refrigeration system used outdoors and related to its surrounding ambient temperatures. In comparison, the water-cooled system is a refrigeration system used indoors.
What is an air conditioner?
An air conditioner provides cold air inside your home or enclosed space by actually removing heat and humidity from the indoor air. It returns the cooled air to the indoor space, and transfers the unwanted heat and humidity outside.
What is HVAC used for?
HVAC stands for heating, ventilation, and air conditioning. It refers to the systems that regulate and move heated and cooled air throughout residential and commercial buildings, from homes to offices to indoor stadiums.
What refrigeration means?
refrigeration, the process of removing heat from an enclosed space or from a substance for the purpose of lowering the temperature.
What are disadvantages of refrigeration?
Disadvantages of air refrigeration system Running cost is high. The mass of air required to circulate in the system is very high when compared to other type of refrigeration cycle due to low specific heat capacity. System components are bulky, large space per ton of refrigeration.
What does AHU mean?
An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system.
What is evaporator in AC?
The evaporator coil is the component in your AC system that absorbs the heat from the air inside your home. It is often either attached to your furnace or located on the inside of your air handler. It works with a condenser coil to complete the heat exchange process that produces cool air.
How does refrigeration work?
Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. You can test this process for yourself by taking some alcohol and putting a drop or two on your skin.
What are the benefits of refrigeration?
Refrigeration slows bacterial growth. Bacteria exist everywhere in nature. They are in the soil, air, water, and the foods we eat. When they have nutrients (food), moisture, and favorable temperatures, they grow rapidly, increasing in numbers to the point where some types of bacteria can cause illness.
