Abstract

The invention relates to a high-efficiency refrigerating system and a refrigerating method thereof. The high-efficiency refrigerating system comprises a first free cooling tower circulating device, tail end equipment and a second free cooling tower circulating device, wherein the first free cooling tower circulating device is used for natural cooling and refrigerating, and the tail end equipment is refrigerated. A heat exchanger is arranged between the first free cooling tower circulating device and the tail end equipment, a water cooling main engine is arranged between the second free cooling tower circulating device and the tail end equipment, and a first water outlet pipe is connected with the heat exchanger; a second water outlet pipe is connected with the water cooling main engine, a first water freezing circulating pump and a second water freezing circulating pump are arranged on the first water outlet pipe and the second water outlet pipe correspondingly, and a branching pipe is arranged between the first water outlet pipe and the second water outlet pipe in a communicating mode; and a first regulating valve is arranged on the branching pipe, and a second regulating valve is further arranged on the second water outlet pipe. According to the high-efficiency refrigerating system and the refrigerating method thereof, the cooling capacity of a cooling tower is fully developed, the cooling efficiency of a whole air-conditioning system is improved, and the operating energy consumption of the air-conditioning system is saved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration systems, and more specifically, relates to a high-efficiency refrigeration system and a refrigeration method thereof. Background technique [0002] In order to reduce the energy consumption of the air conditioning system, more and more systems use cooling towers for direct cooling in transitional seasons and winters, that is, free cooling cooling systems. Its working principle is: in the transitional season and winter, the outdoor ambient temperature is low, directly use the low-temperature outdoor air to cool the cooling water to a lower temperature, and then exchange heat through the heat exchanger to reduce the chilled water to the target temperature , to provide chilled water for the end of the air conditioner. Since the cooling efficiency of the cooling tower is 15-25 times that of the chiller, the cooling provided by the cooling tower will greatly improve the cool...
