Description

Technical Field

[0001] This utility model belongs to the field of refrigeration technology, specifically relating to a chiller system. Background Technology

[0002] In practical applications of chillers, household chillers typically use either submersible pumps or self-priming pumps to circulate the water system. Submersible pumps are characterized by: 1) being installed below the water level and completely submerged; 2) directly drawing water and driving the circulation; 3) generally having a larger flow rate; and 4) having a more compact structure suitable for underwater environments. Self-priming pumps, on the other hand, are characterized by: 1) being installed on the ground or above the water surface; 2) drawing liquid in using their own suction capacity; 3) being primarily used for drawing water from surface sources such as ponds and rivers; 4) having a relatively lower flow rate; and 5) generating more noise during operation. The relatively complex structure of self-priming pumps and their associated noise levels can negatively impact the surrounding environment. Therefore, to achieve higher heat exchange efficiency while considering low noise levels and installation space, designers usually choose submersible pumps. However, selecting a submersible pump requires meeting the pump's requirements regarding water source level and water quality, which presents a new challenge to chiller design.

[0063] Based on the above embodiment, another embodiment is as shown in the following figure: Figure 10 As shown, the cold and hot circulation system 2 comprises a water circulation system 26, a refrigeration circulation loop system 10 and a start-up emptying system 11. The refrigeration circulation loop system 10 is connected with the start-up emptying system 11, the start-up emptying system 11 is connected with the water circulation system 26, and the water circulation system 26 is connected with the water inlet and outlet connecting body 3. The start-up emptying system 11 is used to empty the air remaining in the water circulation system 26.

[0064] Before the refrigeration cycle loop system 10 operates, the starting emptying system 11 is started first, and the air remaining in the water circulation system 26 is emptied, so that the water in the water storage container can flow into the main water pump in the water circulation system 26 under the action of negative pressure, and conditions are provided for the normal start of the main water pump.

Meanwhile, the water chiller submersible pump is difficult to repair after being damaged, and the water chiller needs to be disassembled for repair. If the submersible pump in the water inlet and outlet connecting body is damaged, a new water inlet and outlet connecting body only needs to be configured for the water chiller, and even if the water chiller submersible pump is not repaired, the water chiller can be normally exhausted through the submersible pump in the water inlet and outlet connecting body, and the repair cost is reduced.

[0068] On the basis of the above embodiment, specifically, as shown in Figure 10 After the start-up exhaust system 11 is started up, water enters the main pump 14 from the water inlet 16 of the water chiller, and then enters the refrigeration cycle circuit to be cooled and refrigerated, and then flows out from the water outlet 15 of the water chiller, exchanges heat with the hot water in the water storage container through the water inlet and outlet connecting body 3, and achieves the cooling and refrigeration of the water body.

[0070] After the water body flows into the evaporator 17 through the main pump 14, the evaporator 17 evaporates the low-temperature and low-pressure liquid-phase refrigerant into superheated refrigerant vapor, the compressor 18 is used for compressing the superheated refrigerant vapor into high-temperature and high-pressure gas, and discharging to the condenser 19, the condenser 19 condenses the high-temperature and high-pressure gas into high-pressure liquid, and forms low-temperature and low-pressure supercooled liquid after being reduced in pressure by the throttle valve 20. When the low-temperature and low-pressure supercooled refrigerant liquid passes through the evaporator, the water body entering through the water inlet of the water chiller exchanges heat with the water body in the evaporator 17, and the cooled water body is transported to the water inlet and outlet connecting body 3 through the water outlet 15 of the water chiller, and then enters the water storage container. At the same time, the low-temperature and low-pressure supercooled liquid is gasified into superheated vapor by absorbing heat in the evaporator, and the superheated vapor returns to the compressor again to form a closed refrigeration cycle circuit, so as to realize the refrigeration function.

[0071] In the embodiment, the evaporator 17 adopts water-cooled heat exchange, and high-efficiency heat exchange between the refrigerant and the circulating water of the bathtub is realized through a plate heat exchanger; the condenser 19 adopts air-cooled heat exchange, and forced convection heat exchange between air and high-temperature and high-pressure refrigerant is realized through the condensing fan air exhaust. Figure 10 As shown in the figure, the low-temperature refrigeration water chiller can also include a control panel 21, a shell 22, a fan 23 and the like, the control panel is used for controlling the cold and hot circulating system, and a user can operate the control panel to change the water temperature setting requirement of the bathtub and the ambient temperature.

[0072] The coolant of the closed refrigeration circuit circulates in the closed system and does not contact with the outside air, so that the problems of corrosion and dirt are reduced. Since the coolant circulates in the closed system, the cooling water does not need to be frequently replaced or supplemented, so that the water usage can be significantly reduced. Meanwhile, the closed cooling circuit reduces the energy loss and improves the energy efficiency of the system by recycling the coolant. Furthermore, since the coolant circulates in the closed system, the evaporation problem is avoided, and the stable operation of the system is ensured.
