Water Cooled Condenser High Head Pressure

Here are some facts that you should know about water cooled condensers.

Water cooled condenser high head pressure.

Water cooled condensers involve a heat rejection loop where condenser heat is dissipated to the environment via water. After allowing temperatures to equalize if the refrigerant pressure corresponds to a saturation temperature that equals the water temperature the fouling is on the water side of the tubes and they will need to be cleaned. Of these debris clogging or malfunctioning txvs seem to be the most common. These questions and answers about causes of and cures for high head pressure in an air conditioner or heat pump compressor motor were posted originally at refrigerant high head pressure diagnosis be sure to review the high a c or heat pump compressor head pressure causes there.

Of course other issues can cause high head pressure but these are the most common. As with the ambient 30 average on air cooled condensers ambient will not affect the condensing pressure on water cooled units that is why they are used. Below we list a dozen causes of high head pressure in an air conditioner or heat pump compressor motor. Water cooled condensers and chiller barrels are specialized heat exchangers.

A c or heat pump compressor high head pressure diagnostic faqs. Stop the compressor and maintain water flow through the condenser while observing the refrigerant pressure in the condenser. This phenomenon often occurs in high temperature seasons. The cooling water temperature is too high and the condensation effect is poor.

Plate type heat exchangers a special kind of surface exchanger are also possible but appear to be more common in liquid to liquid heat transfer applications. The rated working condition of the cooling water required by the chiller is 30 35. The condenser fan motor and the condenser coils are the most common problems i have found with the issue of high head pressure. The cooling tower water is 5 degrees warmer than the entering chilled water.

A water cooled condenser is a heat exchanger that removes heat from refrigerant vapor and transfers it to the water running through it. V148 series three way pressure actuated valves regulate water flow to control refrigerant head pressure in systems with single or multiple water cooled condensers. The most common type of water cooled condensers in geothermal power plants are direct contact and surface types. The high water temperature and poor heat dissipation will inevitably lead to high condensation pressure.

When first encountering the problem of high head pressure it is essential to check the basics first. A c or heat pump compressor high head pressure diagnostic checklist 12 causes of high head pressure at an air conditioner heat pump or other refrigeration system. They exchange heat by removing heat from one fluid and transferring it to another fluid. You can expect the suction pressure to be high and the head pressure to be lower than normal because the cooling tower is still operating.
