Abstract: A method for controlling a refrigerating device of a water dispenser. The method includes: S1, controlling a refrigerating module to cool water in a cold water tank; S2, when the temperature of the water in the cold water tank is reduced to a first preset temperature, stopping the refrigerating module at the first preset time; S3, controlling the refrigerating module to work again to continue cooling the water in the cold water tank; S4, when the temperature of the water in the cold water tank is reduced to an nth preset temperature, stopping the refrigerating module at the nth preset time; and S5, determining whether the temperature of the water in the cold water tank reaches a target temperature, and if not, repeating steps S3 and S4 after reaching a predefined number. Through multi-stage refrigeration, an ultra-low temperature refrigeration is achieved.

Abstract: Provided are a refrigeration device and a cold water temperature control method for same. The control method comprises the following steps: controlling a refrigeration device to enter a heat preservation state (S1); detecting a water temperature in a water tank (10) in the refrigeration device (S2); and if the water temperature is greater than a first pre-set temperature, controlling the refrigeration device to carry out a refrigeration operation for a pre-set time so that the water temperature is less than a second pre-set temperature, and controlling the refrigeration device to stop the refrigeration operation after the pre-set time (S3), wherein the second pre-set temperature is less than or equal to the first pre-set temperature. The water temperature control is realized by means of a pre-set time, so that the temperature of cold water can be more precisely controlled.

Abstract: Provided is a water supply apparatus (100) including: a cooling tank (1), a refrigerating systems and a heat exchange device (4). The cooling tank is provided with a cold water outlet (11) and suitable to connected to water source; the refrigeration system comprises a compressor (31), a condenser (32), a throttling device (33) and the evaporator (34). The heat exchange device (4) is arranged outside the cooling tank (1) and provided with a water inlet (41) and a water outlet (42) communicating with the inside of the cooling tank (1), wherein the heat exchange device (4) is constructed such that water in the cooling tank (1) flows into the heat exchange device (4) from the water inlet (41) and performs a heat exchange with the evaporator (34), the water after the heat exchange flows out from the water outlet (42) and flows back to the cooling tank (1).

Abstract: A method and an apparatus for controlling a cooling in a water dispenser are disclosed. The method includes: S1, receiving a cooling instruction and entering a cooling mode according to the cooling instruction; S2, obtaining an operation parameter of the water dispenser; S3, determining whether a suspending condition is satisfied according to the operation parameter; S4, suspending a cooling if the suspending condition is satisfied; and S5, further determining whether a restarting condition is satisfied, performing the cooling and executing steps S2-S5 repeatedly until a cooling terminating condition is satisfied if the restarting condition is satisfied.
