Air-Cooled Condenser The condenser is a heat exchanger where the process heat absorbed by the refrigerant is given off to the air around it. As heat is given off by the high temperature high pressure vapor, its temperature falls until the vapor condenses to a liquid. Motor driven fans gener...
2. SINGLE-EFFECT WATER/LITHIUM BROMIDE ABSORPTION CHILLER A diagram of a single-e!ect absorption chiller is given in Figure 2. In this paper, when the term rich solution is used, it refers to a solution with a high content in refrigerant, in this case water. In Figure 2. Schematic ...
The main equipment, such as the chiller and the circulating water pumps in the machine room, is shown in Figure 10. Figure 9. The water system schematic diagram of variable flow air conditioning. Figure 10. Real picture of the machine room of variable flow air conditioning water system. ...
absorption chiller; ammonia–water; air cooled; residential cooling 1. Introduction In tropical country such as Indonesia, climate conditions are almost constant throughout the year and dominated by high temperatures and humidity [1]. As a result, Indonesia has a significant demand for cooling [2]...
In this respect, in a recent work by the authors [63], it was calculated that to meet this constraint for an air-cooled chiller with a cooling capacity comparable to the one of the HP here considered, Cs should be increased from 600 up to 1500 kJ/°C. For this reason, 1500 kJ/°...
Figure 1. (a) Schematic diagram of the experimental setup, (b) front view of the collector, and (c) cross-sectional view of the collector. A sheet and tube-type water cooling system are applied to absorb excess irradiation for thermal energy conversion. The PV/T system was tilted at an...
Figure 1. Schematic of the proposed integrated power and refrigeration cycle. Initially, the temperature and pressure of the saturated ammonia-water liquid coming from the Kalina absorber (state 1) are increased in pump1, reheating exchangers (RHE) 1 and 2, respectively before entering to the ...
Figure 2. Schematic diagram of the test plate heat exchanger. Table 1. Geometrical parameters of test plate heat exchanger. The performance of the test PHE was measured under the steady-flow condition for 15 min, and the properties of LiBr for measuring the performance of the test PHE wer...
Per Ma and Wang, chiller performance degradation can be detected significantly by using a hybrid quick search (HQS) method through characterizing the PIs of multiple operational parameters, such as the temperature of the condenser water supply [76]. A high chiller's load affects the performance ...
The schematic diagram of the designed hybrid PV/T system is given in Figure 1a. In the designed system, air and water were used as cooling fluids. The schematic of the designed PV/Ts' front view is provided in Figure 1b, where the PV/T system was equipped with a glazed absorber ...
