Performance evaluation of solar and condensing heat recovery systems ...
However, conventional heating, ventilation, and air conditioning (HVAC) systems often overlook the recovery of low-grade waste heat and the integration of renewable energy, resulting in low operational efficiency and high energy costs.
In this study, a system that recovered waste heat from data center's centralized water-cooling system to preheat centralized heating systems was proposed, and the optimal design parameters were investigated, resolving the mismatch between waste heat and building demand. Firstly, parametric analyses were conducted under the design condition of centralized heating. Effects of mass flow rate ...
Energy Analysis of Combi Heat Pump System Configurations for Space ...
Despite this, a critical gap exists as the specific energy performance remains unquantified under diverse operational modes (e.g., heating mode and heat recovery mode). This paper aims to bridge this gap by conducting a comprehensive comparative analysis of two prevalent system configurations while considering feasible proposed control logics.
Performance Analysis of a New Cascade Waste Heat Recovery System With a ...
Abstract. This paper proposes a new cascade waste heat recovery system with low power consumption and the ability to recover waste heat in a wider temperature range, namely, the absorption-compression coupled heat pump system . Simulations were conducted to reveal the effects of generator inlet and outlet water temperatures, supply hot water inlet and outlet water temperatures, and ...
The combination of heat recovery and different energy-efficient systems could contribute to reducing heat loss, stabilizing heat flux, and improving the thermal performance of residential buildings.
