Description

Technical Field

[0001] The utility model relates to the field of water-cooled chillers, in particular to a hydraulic module integrated water-cooled chiller. Background Art

[0002] The water-cooled chiller includes a hot water heater and a chilled water generator. Usually, the hot water heater can heat water to a relatively high temperature, exceeding the temperature of ordinary domestic hot water. Users need to adjust the ratio of the hot water flowing out of the hot water heater to tap water by themselves to obtain hot water at the desired temperature. Since the hot water produced in the hot water heater has a relatively high temperature, the heat exchange rate with the environment is relatively high when it flows in the pipeline, resulting in more heat energy loss.

[0021] In a preferred embodiment, a chilled water generator 21 is connected in series on the hot water heater 11. A fourth electric maintenance gate valve 26 is provided at the inlet end of the chilled water generator 21, a third electric maintenance gate valve 25 is provided at the outlet end of the chilled water generator 21, third water pressure sensors 22 and fourth water pressure sensors 23 are respectively provided at both ends of the fourth electric maintenance gate valve 26, and a chilled water filter 24 is further provided between the third water pressure sensor 22 and the fourth water pressure sensor 23.

[0023] Principle of the hot water generator;

[0024] The water pump in the water-cooled chiller operates to pump water to the hot water filter 14 for impurity filtration, send the clean water to the hot water heater 11 for heating, and then transport it to the user through the upper pipeline. During this process, when the water temperature begins to approach the set value, by adjusting the opening degrees of the first flow regulating valve 12 and the second flow regulating valve 16 to perform real-time control of the flow rate, within the allowable conditions of the system, the customer's outlet water temperature is satisfied to achieve the direct heating function;

[0025] This unit also uses differential pressure to detect water quality, and real-time detection is carried out through the first water pressure sensor 17 and the second water pressure sensor 18. When the detected pressure value reaches the pressure value of the judged cleaning system, by closing the first flow regulating valve 12, the first electric maintenance gate valve 13, and the second flow regulating valve 16, opening the sewage discharge valve 19, and adjusting the frequency of the water pump, the unit is put into the automatic cleaning system mode to keep the water quality inside the system in the best state and keep the heat exchange efficiency of the unit in the best state.

[0026] Principle of chilled water generator:

[0027] The water pump runs to pump water to the chilled water filter 24 for impurity filtration, and then sends the clean water to the chilled water generator 21 for cooling, and then transports it to the user through the upper pipeline. During this process, when the water temperature begins to approach the set value, the opening degrees of the third electric maintenance gate valve 25 and the fourth electric maintenance gate valve 26 are adjusted to control the flow rate in real time, and within the allowable conditions of the system, the chilled water demand of the customer is met.

[0028] This unit also uses differential pressure to detect water quality, and real-time detection is carried out through the third water pressure sensor 22 and the fourth water pressure sensor 23. When the detected pressure value reaches the pressure value of the judged cleaning system, the unit closes the third electric maintenance gate valve 25 and the fourth electric maintenance gate valve 26, opens the sewage discharge valve numbered 27, adjusts the frequency of the water pump, and puts the unit into the automatic cleaning system mode to keep the water quality inside the system in the best state and keep the heat exchange efficiency of the unit in the best state.
