This refers to the temperature difference between the chilled water supply temperature as it exits the chiller compared to the temperature of the refrigerant within the evaporator. for example the chilled water supply temperature might be 7°c (44.6°f) and the refrigerant might be at 3°c (37.4°f) approach therefore equals 4°c or 7.2°f. The engineering mindset was started in 2015 by its founder, paul evans. the mission was to help students, engineers and like minded people learn technical en.

Heat exchanger approach temperature is the difference between required outlet temperature of the process fluid and the temperature at which utility is available. the heat exchanger temperature profile shown in the image above includes two fluids one hot process fluid and other is cooling water (utility). The chilled water outlet temperature was traditionally fixed, usually somewhere around 6°c or 42.8°f but it’s common practice now to apply a chilled water reset strategy. the chilled water reset allows the temperature of the chilled water to be increased during part load conditions. this reduces the amount of work done by the chillers. Even within a specific industry, techniques can differ. engineering an artifact like a turbofan engine is different from assembling a megasystem like an aircraft, and by extension, a system of systems, such as the air traffic network. the three essential properties of the engineering mind set. 1. A temperature approach is just what its says when the temperature of one stream approaches that of another. this occurs at the inlet and outlet of a shell and tube, and you can get temperature approaches part way along the heat curve if latent heat transfer is taking place. The appoach temperature is how close you can get the process side (hot outlet) to the air side (cold inlet). so, if it is ambient 25oc, unless you have a very large oversurface, you are not going to get 25oc in the process outlet, you are going to get it cooled to, let's say, 30 oc, which is a 5 degree approach.

To transfer heat from the refrigerant coolant temperature difference between the two, and that is the approach of a temperature difference (atd), shown in fig. 21. it must be large enough to provide a flow of heat, necessary to achieve the required system capacity. In the hvac world it is the difference between the inlet temperature of one stream and the outlet temperature of the other. i assume it is named because in a counter flow hx the streams approach each others inlet temperature. so for say a chilled water cooling coil. chilled water comes in at 45 deg f and leaves at 57 deg f. Minimum temperature approach for design posted in student: i read for the design of shell & tube heat exchanger , the minimum "approach" should be 10 c . what is "approach" here . whether it is 1) hot fluid outlet temperature cold fluid outlet temperature or2) hot fluid outlet temperature cold fluid inlet temperature or3) hot fluid inlet temperature cold fluid outlet temperature.

We're considering some work to reduce the condenser approach temp. e.g 6°f to 1.6°f. in order to move forward i need to calculate the cost savings. the system has a water cooled centrifugal chiller. can the cost savings be calculated by using site data e.g. gpm, temperatures, power cost?.

Approach point is the difference between the temperature of water at the exit of the economizer, and that of saturation at the evaporator drum pressure; a difference is desired to avoid earlier.
