Abstract
Heat-and-cold recovery system based on liquid cooling data center (energy storage power station) includes high-temperature heat pump, pressure-less heat-storage tank, pressurized heat-storage tank, absorption-type water chiller group, compression-type water chiller group, water cold-storage tank, and PCM cold-storage tank. High-temperature heat pump forms circulating heat-exchange loops with CDU and with pressure-less heat-storage tank; hot-water output interface of pressure-less heat-storage tank connects to pressurized heat-storage tank through first circulating pump set and pipeline heater sequentially; pressurized heat-storage tank stores and outputs hot water/steam; pressurized heat-storage tank connects to absorption-type water chiller group through second circulating pump set and forms circulating heat-exchange loop with pressure-less heat-storage tank through absorption-type water chiller group; absorption-type water chiller group forms circulating heat-exchange loop with computer-room air-cooling region; compression-type water chiller group connects to water/PCM cold-storage tank, which stores cooling water of compression-type water chiller group for heat exchange to CDU a…
