The condenser pressure and temperature affect the performance of the heat pump cycle and the overall system. Figure 3.15 shows the effect of increasing condenser inlet pressure on the exergy efficiency and energetic COP of the heat pump cycle. When the inlet pressure is raised from 1600 kPa to 1800 kPa, the exergy efficiency of the heat pump cycle rises from 41% to 43% and energetic COP rises ...

Logarithmic Mean Temperature Difference – LMTD. In order to solve certain heat exchanger problems, engineers often use a logarithmic mean temperature difference (LMTD), which is used to determine the temperature driving force for heat transfer in heat exchangers.LMTD is introduced due to the fact, the temperature change that takes place across the heat exchanger from the entrance to the exit ...

Figure 7.18 Temperature profiles in a counter-current and a co-current condenser with a "glide" refrigerant. For counter-current flow, the temperature convergence is avoided thanks to the decreasing condensation temperature. However, for co-current flow, the temperature difference between condensate and secondary fluid decreases rapidly.

We’ll look at each of their roles in putting cold air into your car, and also examine the differences between each. First, a brief primer on what your typical A/C system does: 1.Refrigerant is compressed, which increases the refrigerant temperature. 2.Refrigerant travels through the condenser, where the cooling process begins.

Steam Condenser performance and loss diagnostic 1. Pichai Chaibamrung 2. Introduction This report is intent to guide engineer, operator, or technician to diagnose poor condenser vacuum in thermal power plant. A slightly increase condenser pressure result in a huge loss due to increasing plant heat rate.

• ### Chiller Condenser - The Engineering Mindset

The condenser water enters at around 27 ° C (81 ° F) so the refrigerant needs to be a greater temperature than this. If the refrigerant is the same temperature as this return condenser water then the chiller will not be able to reject any heat that’s been picked up in the building, and so the building will be unable to cool down.

Note that, there is always a temperature difference between (around ΔT = 14°C) the condenser temperature and the ambient temperature, which originates from finite size and efficiency of condensers. Since neither the condenser is 100% efficient heat exchanger, there is always a temperature difference between the saturation temperature (secondary side) and the temperature …

• ### Condenser (heat transfer) - Wikipedia

The temperature of the working fluid stays relatively constant during condensation, which maximizes the temperature difference between the working and secondary fluid. Examples of condensers. A surface condenser is one in which condensing medium and vapors are physically separated and used when direct contact is not desired.
