What is friction in a pump system (cont.)

Another cause of friction is all the fittings (elbows, tees, y's, etc) required to get the fluid from point A to B. Each one has a particular effect on the fluid streamlines. For example in the case of the elbow, the fluid particles that are closest to the tight inner radius of the elbow lift off from the pipe surface forming small vortices that consume energy. This energy loss is small for one elbow but if you have several elbows and other fittings the total can become significant. Generally speaking they rarely represent more then 30% of the total friction due to the overall pipe length.

Energy and head in pump systems

Energy and head are two terms that are often used in pump systems. We use energy to describe the movement of liquids in pump systems because it is easier than any other method. There are four forms of energy in pump systems: pressure, elevation, friction and velocity.

Pressure is produced at the bottom of the reservoir because the liquid fills up the container completely and its weight produces a force that is distributed over a surface which is pressure. This type of pressure is called static pressure. Pressure energy is the energy that builds up when liquid or gas particles are moved slightly closer to each other and as a result they push outwards in their environment. A good example is a fire extinguisher, work was done to get the liquid into the container and then to pressurize it. Once the container is closed the pressure energy is available for later use.


Elevation energy is the energy that is available to a liquid when it is at a certain height. If you let it discharge it can drive something useful like a turbine producing electricity.

Friction energy is the energy that is lost to the environment due to the movement of the liquid through pipes and fittings in the system.


Velocity energy is the energy that moving objects have. When a baseball is thrown by a pitcher he gives it velocity energy also called kinetic energy. When water comes out of a garden hose, it has velocity energy.

 

 

Figure 9a


In the figure above we see a tank full of water, a tube full of water and a cyclist at the top of a hill. The tank produces pressure at the bottom and so does the tube. The cyclist has elevation energy which he will be using as soon as he moves.

As we open the valve at the tank bottom the fluid leaves the tank with a certain velocity, in this case pressure energy is converted to velocity energy. The same thing happens with the tube. In the case of the cyclist, the elevation energy is gradually converted to velocity energy.


The three forms of energy: elevation, pressure and velocity interact with each other in liquids. For solid objects there is no pressure energy because they don’t extend outwards like liquids filling up all the available space and therefore they are not subject to the same kind of pressure changes.


The energy that the pump must supply is the friction energy plus the elevation energy.


PUMP ENERGY = FRICTION ENERGY + ELEVATION ENERGY

Chiller plant design can be challenging; one may not know where to start. Below are the five design considerations to get going.

  1. Type of Chiller
    You have to decide between air-cooled vs. water cooled; centrifugal vs modular. Air-cooled are good when you have space outside but limited space indoors. Air-cooled tend to be less expensive but require outdoor space and can be loud. Water-cooled are more expensive and require the addition of cooling towers and condenser water.

    Centrifugal tend to have a much large footprint but are more efficient and cost effective for large systems. Modular chillers allow for chilled water when there is a limited square footage available and are great for retrofits.
  2. Pressures
    Standard equipment is rated for 125 psi. Pressures tend to become a concern in buildings taller than about 280 feet tall and the chiller plant is located at the top or the bottom of the system, or when the greatest working pressures exceed the 125 rated capacity. When this condition occurs, the designer must look into providing a pressure break through a heat exchanger or look to locate the chiller plant in a central location. In tall and super-tall buildings, pressures can exceed 300 psi, and the chilled water system may require multiple pressure breaks. In these situations, the floor on which the chiller plant is located on becomes critical.
  3. Temperatures
    Typical temperature deltas for chilled water systems range between 10 and 16 degrees. Supply temperatures range between 38 degs F and 44 degs F. Lower supply temperatures and higher delta Ts result in smaller coils at air handling units and terminal units but result in higher energy consumption at the chiller. Tall buildings requiring multiple pressure breaks require the use of lower design temperature because at each pressure break, two degrees of temperature are lost.
  4. Operation
    It is best to talk with the building operator to determine when the chiller plant will need to operate. Are there critical loads that will require cooling 24/7, 365 or is the chilled water system responsible for space cooling and will only operate during the summer? One also has to consider the load profile the chiller will see. The operation of the system will rarely be constant, and the equipment must be capable of turning down to meet low load conditions.
  5. Pumping
    For large systems, the piping system is typically variable, primarily because there is a lower upfront cost and lower energy use. For modular chillers, primary-secondary pumping arrangements can be beneficial due to the need to maintain minimum flow through the chiller on low load days to avoid cycling the chiller or turning off due to low flow. Primary secondary remains a good option for modular chillers when the load profile is constant.
