Effect of Compressor-Discharge-Cooler Heat-Exchanger Length Using Condensate Water on the Performance of a Split-Type Air Conditioner Using R32 as Working Fluid

Energies, 2022
The utilization of condensate water as a compressor-discharge cooler results in subcooling on the condenser outlet. On the other hand, a split-type air conditioner (A/C) with R32 as working fluid can provide higher compressor-discharge temperatures than ...

Study on the Cooling Capacity of Different Quenchant

Procedia Engineering, 2012
AbstractHeat treatment is one method to improve mechanical properties of metal, but each heat treatment method has its advantages and disadvantages, therefore, different requirements regarding size, shape, and properties with respect to different heat treatment processes should be considered.

High temperature exposure increases plant cooling capacity [PDF]

Current Biology, 2012
SummaryPlants inhabit different environments and have evolved mechanisms to optimise growth within defined temperature ranges. In Arabidopsis thaliana, growth at high temperature (28°C) results in striking elongation of stems and increased leaf elevation from the soil surface [1–3].

Fault Detection Algorithm for Multiple-Simultaneous Refrigerant Charge and Secondary Fluid Flow Rate Faults in Heat Pumps

Energies, 2021
The detection and diagnosis of faults is becoming necessary in ensuring energy savings in heat pump units. Faults can exist independently or simultaneously in heat pumps at the refrigerant side and secondary fluid flow loops. In this work, we discuss the

The impacts of water capacity and air capacity to condensation temperature in cooling tower [PDF]

AIP Conference Proceedings, 2016
Exergy analysis includes a psychrometric process, such as in the operations of the cooling tower. The total exergy can be split into both chemical and thermomechanical components, therefore enabling one to quantify the contribution of each term to the total exergy through the tower. The total exergy content of a material stream is calculated by summing
