Abstract

The invention relates to a cold water unit and a control method thereof. The cold water unit comprises a compressor (1), a condenser (2), a throttling component (3), an evaporator (4), a storage box (5), a heating pipe (6) and an electric heating device (7), wherein the condenser (2) is connected to the compressor (1), the throttling component (3) is connected to the condenser (2), the evaporator(4) is connected between the throttling component (3) and the compressor (1), the storage box (5) stores a cooling liquid internally, the cooling liquid exchanges heat with a heat exchanging medium inthe condenser (2) to cool the heat exchanging medium, the heating pipe (6) is arranged at the bottom of the storage box (5), a heating medium circulates in the heating pipe (6) and is used for heating the cooling liquid, and an electric heating device (7) is arranged at the bottom of the storage box body (5) and is configured to heat the cooling liquid by electric energy heating. The cold water unit can prevent the cooling liquid from icing effectively, so that the demand of using the cold water unit all over the year can be met.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a chiller and a control method thereof. Background technique [0002] Evaporative condenser is a high-efficiency and green refrigeration technology that uses the temperature difference between dry and wet bulbs as the driving force. It can be applied to evaporative chillers to cool the refrigerant in the heat exchange tube through indirect evaporative cooling. For occasions with year-round cooling needs, in winter, the water in the water tank will freeze, which will affect the normal use of the unit. [0003] It should be noted that the information disclosed in the background technology section of the present invention is only intended to increase the understanding of the general background of the present invention, and should not be considered as an acknowledgment or in any form to imply that the information constitutes knowledge already known to those skilled in the art. ...
