Cooling unit and air-cooled chiller unit with cooling unit

Abstract

The invention relates to the technical field of refrigerating equipment, in particular to a cooling unit and an air-cooled chiller unit with the cooling unit. The invention provides the cooling unit which comprises a natural cold source subunit and a condenser subunit that are arranged in parallel, wherein the inlet end of the natural cold source subunit is connected with a water return pipe at the tail end of an air conditioner, and the outlet end of the natural cold source subunit is connected with a chilled water inlet of the chiller unit; the natural cold source subunit comprises a W-shaped natural cold source structure formed by four natural cooling coiled pipes; the condenser subunit comprises a W-shaped condenser structure formed by four condensing coiled pipes; and the W-shaped natural cold source structure is arranged at the periphery of the W-shaped condenser structure. In winter or transitional seasons, just by independent cooling of a natural cold source or the combined application of the natural cold source for cooling and a compressor for mechanical cooling, the annual operating energy consumption of the air-cooled chiller unit can be greatly reduced, and an energy saving rate of 20-70% can be achieved according to differences of weather conditions of application areas.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular to a cooling unit and an air-cooled chiller equipped with the cooling unit, in particular to a cooling unit capable of reducing energy consumption of air-conditioning refrigeration and an air-cooled chiller equipped with the cooling unit . Background technique [0002] In recent years, with the continuous development of the Internet, a large number of data centers have been put into use, and the resulting huge power consumption has attracted more and more attention. The energy saving and consumption reduction of data centers has become a key issue. Among them, the energy consumption of air conditioners accounts for nearly 40% of the total energy consumption of data centers. Data centers have the characteristics of uninterrupted cooling throughout the year. In data centers that use chilled water-type air conditioners, chillers need to run all year round. Whe...
