What is the purpose of a desuperheater?

What is the purpose of a desuperheater?

The primary function of a desuperheater is to lower the temperature of superheated steam or other vapors. This temperature reduction is accomplished as a result of the process vapor being brought into direct contact with another liquid such as water. The injected water is then evaporated.

What is a desuperheater HVAC?

Desuperheaters, or recuperaters, operate by utilizing the high-pressure, superheated discharge gas temperature to heat water. The cooling of the discharge gas normally represents 15-25% of the total heat of rejection.

How do you calculate desuperheater?

Calculation Details

  1. Step 1: Determine Inlet Steam Properties.
  2. Step 2 ‘If NO Desuperheating’: Determine Outlet Steam Properties.
  3. Step 2 ‘If Desuperheating’: Determine Cooling Water Properties.
  4. Step 3: Determine Desuperheated Outlet Steam Properties.
  5. Step 4: Determine Feedwater and Outlet Mass Flows.

What is the significance of desuperheater in a domestic refrigerator?

A desuperheater is a device that cools down the superheated refrigerant (gas that is at a temperature above its saturation temperature). The temperature of this gas is reduced by spraying droplets of water into the flow of the superheated gas.

How do you hook up a desuperheater to your water heater?

Attach the center port of the ¾” FPT tee to the opposite end of the brass nipple. Attach the ½” SWT x ¾” MPT cooper adaptor to the side of the tee closet to the unit. Attach the drain valve on the tee opposite the adapter. Cut the cold water IN line going to the water heater.

How much does a desuperheater cost?

The Desuperheater Pump is USD195. 00 and the cost for the Desuperheater option is USD425.

What is chiller desuperheater?

Desuperheater – recovering the heat from the super-heated refrigerant gas at the compressor outlet.

What is the difference between desuperheater and Attemperator?

An attemporator controls the steam temperature while a desuperheater removes whatever superheat there is in steam and reduces the temperature to a point at or nearly at saturation temperature.

How does a geothermal water heater work?

A geothermal system uses small-diameter, High-Density Polyethylene (HDPE) pipes buried underground called a “loop.” The loop circulates water to move heat energy to and from your home. It’s the heart of a geothermal system and its biggest advantage over ordinary heat pumps, air conditioners and fossil fuel furnaces.

Does desuperheater work in winter?

A desuperheater does not affect the heat output of the geothermal system in the winter. Geothermal systems have safeguards that prevent the desuperheater from operating when that heat is needed for heating the building.

What is a steam desuperheater?

A desuperheater device injects a controlled amount of water into the superheated steam. The steam temperature is reduced by evaporative cooling from the water being injected into the superheated steam thereby lowering the temperature to allow for more efficient downstream use of the steam.

What is the purpose of Attemperator of a boiler?

Boiler attemperators are used to fine tune / control steam temperature from a boiler, as well as the steam temperature between boiler stages.
