Description

Technical Field

[0001] This utility model relates to the field of chillers, specifically a high-precision chiller with ambient temperature-responsive temperature control. Background Technology

[0002] A chiller is a water cooling device that provides cooling water at constant temperature, flow rate, and pressure. The working principle of a chiller involves first injecting a certain amount of water into the internal water tank. The chiller's refrigeration system then cools the water, and a water pump delivers the low-temperature cooling water to the equipment requiring cooling. The chilled water carries away heat, its temperature rises, and it flows back to the water tank, achieving the cooling effect. Chiller technology is the driving force behind enterprise development; continuous innovation is essential to injecting fresh vitality into the enterprise and maintaining its leading position in the industry.

[0003] The existing device has the following shortcomings when in use: when the ambient temperature is high, the temperature of the air blown towards the condenser is also high, which reduces the condensation effect. It cannot respond to the ambient temperature to adjust the operation of the chiller, thus affecting the chiller's cooling efficiency and effect. When water comes into contact with the evaporator for heat exchange, impurities in the water are easy to adhere and accumulate, affecting the heat exchange efficiency of the evaporator, thereby affecting the cooling efficiency and effect. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision chiller with ambient temperature response control to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision chiller with ambient temperature response control, comprising a chiller casing, a water tank, condenser B, condenser A, and an air inlet. A compressor is installed in the chiller casing. A tee is installed at one end of a copper connecting pipe mounted on the compressor. An electrically controlled valve B and an electrically controlled valve A are respectively installed at the two openings of the tee. The two openings of the tee are connected to condenser B and condenser A respectively via pipes. A tee is installed at one end of a copper pipe mounted on a dryer filter. A control valve A and a control valve B are respectively installed at the two openings of the tee. The two openings of the tee are connected to condenser B and condenser A respectively via pipes. An air inlet is provided on the chiller casing, and a temperature sensor is installed at the air inlet. A controller is installed on the chiller casing.

[0006] Using the above technical solution, when the chiller is working, the temperature sensor can detect the temperature at the air inlet in real time and transmit the detected temperature signal to the controller. The controller analyzes and processes the received temperature signal. When the temperature at the air inlet is lower than the preset temperature threshold, the controller controls the opening of the electronic control valve A and the closing of the electronic control valve B. Simultaneously, control valve A is opened and control valve B is closed, allowing the refrigerant output from the compressor to flow through the condenser A and be condensed and cooled by the cooling fan. When the temperature at the air inlet is higher than the preset temperature threshold, the controller controls the closing of the electronic control valve A and the opening of the electronic control valve B. Simultaneously, control valve A is closed and control valve B is opened, allowing the refrigerant output from the compressor to flow through the condenser B and be cooled by the cooling fan. The water tower condenses and dissipates heat from the refrigerant in condenser B, ensuring its normal operation. After being filtered by a dryer filter, the refrigerant undergoes pressure reduction via a throttling valve before entering the evaporator. In the evaporator, the refrigerant absorbs heat from the water in the water tank, thus cooling the water. The cooled water is then output through the chilled water outlet pipe for use by the equipment. Simultaneously, uncooled water flows back to the water tank through the chilled water return pipe, forming a circulating cooling system. When the ambient temperature is high and the air temperature blowing towards the condenser is also high, the system can respond to the ambient temperature and automatically adjust the operating status of the two condensers to ensure that the chiller maintains a high-efficiency operating state under different ambient temperatures, effectively improving the chiller's cooling efficiency and effect.

[0007] Preferably, a water tank is installed in the casing of the chiller, a cold water return pipe and a cold water outlet pipe are installed on the water tank, a water pump is installed on the cold water outlet pipe, and a filter ring A is installed on the cold water return pipe.

[0008] By adopting the above technical solution, the water pump can ensure that the cooled water is stably output through the cold water outlet pipe. The filter ring A is used to filter the water flowing back to the water tank, avoiding the problem of impurities in the water adhering and accumulating, which affects the heat exchange efficiency of the evaporator. This improves the cooling efficiency and effect of the chiller and ensures the efficient and stable operation of the equipment.

[0009] Preferably, a cooling fan is installed on one side of the condenser A in the chiller housing, a filter plate is installed at the air inlet, and an air outlet is provided on the chiller housing.

[0010] By adopting the above technical solution, the cooling fan can accelerate the heat dissipation of condenser A and improve the condensation efficiency. The filter plate can effectively block external dust and debris from entering the chiller, avoiding contamination and damage to condenser A and other internal components. The air outlet ensures that the hot air after condenser A dissipates heat can be smoothly discharged, preventing hot air from accumulating inside the chiller and affecting the condensation effect and stable operation of the equipment. These designs together constitute the chiller's efficient heat dissipation system, ensuring that the chiller can maintain a stable operating state under different ambient temperatures, thus improving the reliability and service life of the equipment.

[0011] Preferably, the condenser B is equipped with a water inlet pipe and a water outlet pipe, the water inlet pipe is equipped with a filter ring B, and the water inlet pipe and the water outlet pipe are connected to a cooling tower.

[0012] By adopting the above technical solution, the filter ring B can filter the water entering the condenser B, preventing impurities from affecting the heat exchange performance of the condenser B. The inlet and outlet water pipes are connected to a cooling tower to form a circulating cooling system, which enables the heat medium in the condenser B to be efficiently cooled through the cooling tower, providing a strong guarantee for the stable operation of the chiller.

[0013] Preferably, an evaporator is installed in the water tank, the evaporator is connected to the compressor, the evaporator is connected to a throttle valve installed in the chiller housing, and the throttle valve is connected to the dryer filter.

[0014] Using the above technical solution, the refrigerant is filtered through a dryer filter and then depressurized by a throttling valve before entering the evaporator. Inside the evaporator, the refrigerant absorbs heat from the water in the water tank, thereby cooling the water. The cooled water is then supplied to other equipment.

[0015] Preferably, the controller is connected to the various components in the chiller.

[0016] Using the above technical solution, the controller is connected to various components in the chiller to monitor and regulate the operation and switching of the two cooling systems.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. When the chiller is working, the temperature sensor can detect the temperature at the air inlet in real time and transmit the detected temperature signal to the controller. The controller analyzes and processes the received temperature signal and can respond according to the ambient temperature, automatically adjusting the working status of the two sets of condensers to ensure that the chiller can maintain a high-efficiency operating state under different ambient temperatures, effectively improving the cooling efficiency and effect of the chiller.

[0019] 2. Filter ring A is used to filter the water returning to the water tank, preventing impurities in the water from adhering and accumulating, which would affect the heat exchange efficiency of the evaporator. This improves the cooling efficiency and effect of the chiller and ensures the efficient and stable operation of the equipment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-4 This utility model provides an embodiment of a high-precision chiller with ambient temperature response control, comprising a chiller housing 1, a water tank 2, a condenser B15, a condenser A19, and an air inlet 24. A compressor 8 is installed in the chiller housing 1. A copper connecting pipe 9 mounted on the compressor 8 has a T-joint 12 at one end. Two openings of the T-joint 12 are respectively equipped with an electrically controlled valve B13 and an electrically controlled valve A14. The two openings of the T-joint 12 are connected to the condenser B15 and the air inlet 24 via pipes. The condenser A19 is connected, and a three-way connector 20 is installed at one end of the copper pipe 23 installed on the dryer filter 11. The two openings of the three-way connector 20 are respectively provided with control valve A21 and control valve B22. The two openings of the three-way connector 20 are connected to the condenser B15 and condenser A19 respectively through pipes. An air inlet 24 is opened on the chiller housing 1, and a temperature sensor 25 is installed at the air inlet 24. A controller 26 is installed on the chiller housing 1.

[0027] When the chiller is working, the temperature sensor 25 can detect the temperature at the air inlet 24 in real time and transmit the detected temperature signal to the controller 26. The controller 26 analyzes and processes the received temperature signal. When the temperature at the air inlet 24 is lower than the preset temperature threshold, the controller 26 controls the solenoid valve A14 to open and the solenoid valve B13 to close. At the same time, it opens control valve A21 and closes control valve B22, so that the refrigerant output from the compressor 8 flows through the condenser A19 and is condensed and cooled by the cooling fan 28. When the temperature at the air inlet 24 is higher than the preset temperature threshold, the controller 26 controls the solenoid valve A14 to close and the solenoid valve B13 to open. At the same time, it closes control valve A21 and opens control valve B22, so that the refrigerant output from the compressor 8 flows through the condenser A19 and is cooled by the cooling fan 28. Condenser B15 uses a cooling tower to condense and dissipate heat from the refrigerant within it, ensuring its normal operation. The refrigerant is filtered through a dryer filter 11 and then depressurized by a throttle valve 10 before entering the evaporator 3. In the evaporator 3, the refrigerant absorbs heat from the water in the water tank 2, thus cooling the water. The cooled water is then output through the cold water outlet pipe 7 for use by the equipment. Simultaneously, uncooled water flows back to the water tank 2 through the cold water return pipe 4, forming a circulating cooling system. When the ambient temperature is high and the air temperature blowing towards the condenser is also high, the system can respond to the ambient temperature and automatically adjust the operating status of the two condensers to ensure that the chiller maintains a high-efficiency operating state under different ambient temperatures, effectively improving the cooling efficiency and effect of the chiller.

[0028] A water tank 2 is installed inside the chiller casing 1. A chilled water return pipe 4 and a chilled water outlet pipe 7 are installed on the water tank 2. A water pump 6 is installed on the chilled water outlet pipe 7, and a filter ring A5 is installed on the chilled water return pipe 4. The water pump 6 ensures a stable output of cooled water through the chilled water outlet pipe 7. The filter ring A5 filters the water returning to the water tank 2, preventing impurities from accumulating and affecting the evaporator's heat exchange efficiency. This improves the chiller's cooling efficiency and effect, ensuring efficient and stable operation of the equipment.

[0029] A cooling fan 28 is installed on one side of the condenser A19 within the chiller housing 1. A filter plate 27 is installed at the air inlet 24, and an air outlet 29 is provided on the chiller housing 1. The cooling fan 28 accelerates the heat dissipation of the condenser A19, improving condensation efficiency. The filter plate 27 effectively prevents external dust and debris from entering the chiller, avoiding contamination and damage to the condenser A19 and other internal components. The air outlet 29 ensures that the hot air from the condenser A19 can be smoothly discharged, preventing hot air from accumulating inside the chiller and affecting the condensation effect and stable operation of the equipment. These designs together constitute the chiller's efficient heat dissipation system, ensuring that the chiller maintains stable operation under different ambient temperatures, thus improving the equipment's reliability and service life.

[0030] The condenser B15 is equipped with an inlet pipe 16 and an outlet pipe 18. A filter ring B17 is installed on the inlet pipe 16. The inlet pipe 16 and the outlet pipe 18 are connected to a cooling tower. The filter ring B17 filters the water entering the condenser B15, preventing impurities from affecting the heat exchange performance of the condenser B15. The inlet pipe 16 and the outlet pipe 18, connected to the cooling tower, form a circulating cooling system, allowing the heat transfer medium in the condenser B15 to be efficiently dissipated through the cooling tower, providing a strong guarantee for the stable operation of the chiller.

[0031] An evaporator 3 is installed in the water tank 2. The evaporator 3 is connected to the compressor 8 and to a throttle valve 10 installed in the chiller casing 1. The throttle valve 10 is connected to a dryer filter 11. The refrigerant is filtered through the dryer filter 11 and then depressurized by the throttle valve 10 before entering the evaporator 3. In the evaporator 3, the refrigerant absorbs heat from the water in the water tank 2, thereby cooling the water. The cooled water is then supplied to other equipment.

[0032] The controller 26 is connected to various components in the chiller. Through this connection, the controller 26 monitors and regulates the operation and switching between the two cooling systems.

[0033] The control modules and electronic components involved in this application are all existing mature technologies, and there are many products on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or through conventional use. The protection content of this application does not involve the improvement of controller software and methods, so the models of electronic components and the control process of the control system will not be described in detail here.

[0034] Working Principle: When the chiller is working, the temperature sensor 25 can detect the temperature at the air inlet 24 in real time and transmit the detected temperature signal to the controller 26. The controller 26 analyzes and processes the received temperature signal. When the temperature at the air inlet 24 is lower than the preset temperature threshold, the controller 26 controls the solenoid valve A14 to open and the solenoid valve B13 to close. At the same time, it opens control valve A21 and closes control valve B22, so that the refrigerant output from the compressor 8 flows through the condenser A19 and is condensed and cooled by the cooling fan 28. When the temperature at the air inlet 24 is higher than the preset temperature threshold, the controller 26 controls the solenoid valve A14 to close and the solenoid valve B13 to open. At the same time, it closes control valve A21 and opens control valve B22, so that the refrigerant output from the compressor 8 flows through the condenser A19 and is condensed and cooled by the cooling fan 28. The refrigerant in condenser B15 is condensed and cooled by the cooling tower to ensure its normal operation. After being filtered by the dryer filter 11, the refrigerant is depressurized by the throttle valve 10 and then enters the evaporator 3. In the evaporator 3, the refrigerant absorbs heat from the water in the water tank 2, thereby cooling the water. The cooled water is output through the cold water outlet pipe 7 for use by the equipment. At the same time, the uncooled water flows back to the water tank 2 through the cold water return pipe 4, forming a circulating cooling system. When the ambient temperature is high and the air temperature blown towards the condenser is high, the system can respond according to the ambient temperature and automatically adjust the working state of the two condensers to ensure that the chiller can maintain a high-efficiency operating state under different ambient temperatures, effectively improving the cooling efficiency and effect of the chiller.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
