Quick Answer: What Is Difference Between Condenser And Heat Exchanger?

What are the three functions of a condenser?

A condenser’s function is to allow high pressure and temperature refrigerant vapor to condense and eject heat.

There are three main types: air-cooled, evaporative, and water-cooled condensers..

How do you calculate condenser capacity?

Step 4: Condenser Selection Condenser capacities (for 60 Hz) are located in Table 4. These capacities are given in MBH/°TD. Convert the THR calculated in step 2 to MBH/°F TD by dividing by 1,000 to get THR in MBH. Then divide the THR by the design TD to get MBH/°F TD.

How do I choose a condenser?

The evaporation ranges of each compressor and, therefore, of every condensing unit, vary from one to another. So, when choosing the CU, you should always check the evaporation range that the compressor is approved to work. It is possible to assess by means of technical data sheets.

What is the difference between a compressor and a condenser?

The gaseous refrigerant moves to the outdoor unit. Condenser coils in the outdoor unit house the refrigerant during its return to liquid form. The compressor increases pressure on the gas, causing it to condense into liquid. As the refrigerant changes state, it release the heat it contains.

What is the principle of condenser?

The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid. It does it by heat transfer, or the principle that heat will always move from a warmer to a cooler substance.

What type of condenser is the most efficient?

Water-cooled units are the most efficient type of condenser you can install. Among water-cooled condensers, there are three types: shell and tube, shell and coil and double tube. Most commonly, the shell and tube types are implemented. They require less power per ton of refrigeration, so they use less power.

Is a condenser a heat exchanger?

Condenser and Heat Exchangers: A condenser is an apparatus intended to condense vapors to a liquid state from their gaseous state. … A heat exchanger works to conduct heat from a substance of higher temperature to a substance of lower temperature without phase changes.

What are the types of heat exchanger?

What are the different types of heat exchanger?Parallel-flow and counter-flow heat exchanger.Finned and Unfinned tubular heat exchanger.U-tube, single pass straight and two pass straight heat exchanger.Plate-and-frame heat exchanger.Pate-fin heat exchanger.Microchannel heat exchanger.

How do I choose a heat exchanger?

The following criteria can help in selecting the type of heat exchanger best suited for a given process:Application (i.e. sensible vapor or liquid, condensing or boiling)Operating pressures & temperatures (including startup, shutdown, normal & process upset conditions)More items…

Can I replace just the AC condenser?

Your Condenser Unit Could Solely Be to Blame for a Broken AC A common question we get is if you can replace just the condenser. The short answer is yes, you can. Some technicians often do in some cases. … When you replace the condenser unit along, you’ll have old components mixed with the new.

What type of heat exchanger is a condenser?

It is a shell and tube heat exchanger installed at the outlet of every steam turbine in thermal power stations. Commonly, the cooling water flows through the tube side and the steam enters the shell side where the condensation occurs on the outside of the heat transfer tubes.

What is condenser capacity?

The condenser capacity is the ability of the condenser to transfer heat from the hot vapour refrigerant to the condensing medium. … The heat transfer capacity of a condenser greatly depends upon the temperature difference between the condensing medium and the vapour refrigerant.

What is h in heat transfer?

The approximate rate of heat transfer between the bulk of the fluid inside the pipe and the pipe external surface is: where q = heat transfer rate (W) h = convective heat transfer coefficient (W/(m2·K)) t = wall thickness (m) k = wall thermal conductivity (W/m·K) A = area (m2) = difference in temperature.

What is the function of a condenser in a car?

The air-conditioning condenser is a radiator positioned between the car’s grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state. The liquid refrigerant flows to the evaporator inside the dashboard, where it cools the cabin.

What is the most effective heat exchanger?

Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important. However, a plate heat exchanger regenerator is restricted to low viscosities. With high viscosities, a special tubular may be required.

What is the duty of a heat exchanger?

18. 5 Heat Exchangers. The general function of a heat exchanger is to transfer heat from one fluid to another. The basic component of a heat exchanger can be viewed as a tube with one fluid running through it and another fluid flowing by on the outside.

What is the difference between condenser and evaporator?

While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid.

How does a condenser and evaporator work?

The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. … This causes the refrigerant to absorb heat from the warm air and reach its low boiling point rapidly. The refrigerant then vaporizes, absorbing the maximum amount of heat.
