An integrated cooling system, composed of a VC cycle and a pump-driven heat pipe (PHP) cycle, allows the VC cycle to be turned off when the cold source temperature is low, which can reduce energy use. However, the PHP cycle only operates efficiently under specific low-temperature conditions, and this restricts the annual energy-saving potential. This paper proposes a novel rack-level integrated cooling system to enhance energy-saving potential, which operates in three modes including liquid-pump-driven (LPD), integration-driven (ID) and vapor-compressor-driven (VCD) modes, corresponding to low, medium, and high cold source temperatures, respectively. Compared with a representative PHP/VC system, a gas–liquid separator near evaporator outlet, which operates in all modes, and a subcooler are introduced here. In the tests, the evaporating temperature was set within the range of 23.5–24.0 °C to maintain a server room temperature of 27 °C in accordance with ASHRAE recommendations.

Under even cold source surface temperature distribution, the transparency of the ice body is found negatively correlated with the freezing rate.

However, composition shift between the circulation and the nominal composition in blends, necessitate accurate measurement of the circulation composition. This study reviews existing <em>ex-situ</em> and <em>in-situ</em> methods for measuring circulation composition, and introduces a novel, cost-effective <em>ex-situ</em> measurement technique based on the pressure-temperature-density (PTD) gas method. This method measures binary mixture composition in the presence of oil, with an uncertainty of ±0.02 in mass fraction. It is more portable and affordable than traditional gas chromatography (GC), though with some tradeoffs in accuracy. In a chiller system using R134a and R32 blends, the PTD gas method detects a circulation composition shift of 0.03–0.06 from the nominal value. Additionally, three <em>in-situ</em> estimation techniques – pressure-temperature-quality (PTx), pressure-temperature-enthalpy (PTh), and pressure-temperature-density (PTD) liquid – are evaluated for measuring circulation composition without sample withdrawal. The PTx and PTh methods underestimate composition by 0.02–0.08, while the PTD liquid method overestimates by 0.08–0.12. These discrepancies cause the peak COP to shift relative to the <em>ex-situ</em> PTD gas measurement. The peak COP is 2–3 % lower using nominal composition, PTx and PTh methods, whereas the PTD liquid method overestimates it by nearly 3 %. Thus, calibration of <em>in-situ</em> methods is recommended to enhance accuracy <em>of in-situ</em> methods using an <em>ex-situ</em> technique.

Eight innovative compressor configurations, varying in spiral turns count and injection port placement, are designed and analyzed. A new theoretical model of the compressor's operating cycle is developed, enabling precise simulations of performance under different conditions. The study demonstrates that increasing the number of spiral turns enhances heat generation but reduces the coefficient of performance (COP), while vapor injection technology improves heating performance by 2.4 % to 4.9 % compared to non-injection designs. To further explore the effects of design modifications, three-dimensional simulations are conducted to analyze temperature and pressure distributions at various injection port locations, revealing that compressors with three spiral turns (<em>N</em> = 3.0) exhibit higher internal temperatures, potentially leading to localized high-temperature accumulation near the discharge port. The theoretical model is rigorously validated through experimental testing, confirming its accuracy and providing practical insights for compressor design.
