High Condenser Pressure Chiller. There are usually four cases: Compressor, evaporator, condenser and expansion valve, thus achieving the cooling and heating effect of the unit.
Service Chiller BSD Jasa Service Chiller from www.bravochiller.co.id
As a result, the refrigerant pressure in the condenser is unable. We at maximus chillers have recently carried out air cooled chiller condenser testing at a new 3 year maintenance contract in the north west. Another fairly common problem that can lead to high pressure failures is that the chiller has been overcharged with refrigerant.
When The Condenser Tube Is Dirty, The Heat Exchange Effectiveness Drops Thereby Causing The Refrigerant Not Able To Be Cooled By The Condenser Water Effectively.
The normal installation position is generally low inlet pipe, high outlet pipe, and “low inlet and. Higher head pressure causes more energy as it. Compressor exhaust pressure reflects condensation pressure, and the normal value should be 1.4~1.8mpa, and the protection value should not exceed 2.0mpa.
(C) Too Much Charge In The Refrigeration System (Liquid Recovery In The Condenser).
Suppose the maximum lift of chiller is from 300kpa to 900kpa.that means it takes the refrigerant in from evaporator at pressure of 300kpa & compress it to maximum pressure of 900kpa to. Chiller trip out on high condenser pressure at start up. As a result, the refrigerant pressure in the condenser is unable.
The Three Causes For High Discharge Temperatures Are:
Using the above equation and the ari design conditions, the temperature change in the condenser for modern high efficiency chillers is found to be 9.4 o f at 3 gpm/ton. The evaporator pressure at 42 o f is 36.6 psig. Leave a pressure gauge connected, as it will be necessary for determining progress.
This Article Covers The Basics Of Head Pressure Controls In Chiller Systems.
Another fairly common problem that can lead to high pressure failures is that the chiller has been overcharged with refrigerant. Standard chilled water temperature is 6.7°c (44°f) for supply and 12.2°c (54°f) for return. The last of 4 systems had gone down on the morning that we first attended site.
Sometimes, This Vapor Can Build Up Near The Top, Creating Very High Pressure.
These high discharge pressure chillers can be used in other situations as well. So, identifying the cause of high condenser pressure can lead to the cause of chiller surge. 1.2 mw of cooling had been lost which resulted in the water system temperature rising to 31°c.
