Water Cooled Condenser High Head Pressure

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.

Water cooled condenser high head pressure.

The most common type of water cooled condensers in geothermal power plants are direct contact and surface types. 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. Having the refrigerant vapor condensed on the outside of a tube does this. Of course other issues can cause high head pressure but these are the most common.

The cooling tower water is 5 degrees warmer than the entering chilled water. Of these debris clogging or malfunctioning txvs seem to be the most common. V148 series three way pressure actuated valves regulate water flow to control refrigerant head pressure in systems with single or multiple water cooled condensers. This phenomenon often occurs in high temperature seasons.

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. Here are some facts that you should know about water cooled condensers. Stop the compressor and maintain water flow through the condenser while observing the refrigerant pressure in the condenser. A c or heat pump compressor high head pressure diagnostic faqs.

They exchange heat by removing heat from one fluid and transferring it to another fluid. 2 is there a rule of thumb regarding approximate head pressure based on inlet water temp and delta t across condenser. Water cooled condensers involve a heat rejection loop where condenser heat is dissipated to the environment via water. Below we list a dozen causes of high head pressure in an air conditioner or heat pump compressor motor.

A water cooled condenser is a heat exchanger that removes heat from refrigerant vapor and transfers it to the water running through it. The high water temperature and poor heat dissipation will inevitably lead to high condensation pressure. Use for applications with system water pressures of up to 350 psi 24 1 bar such as high rise buildings. 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.

The cooling water temperature is too high and the condensation effect is poor. 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. 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.
