Description

Technical Field

[0001] This application relates to the field of hydraulic equipment technology, and more specifically, to a high-temperature hot water system and the same. Background Technology

[0002] High-temperature heat pumps, with their superior energy conversion efficiency, have become the core equipment for high-temperature hot water supply. Currently, for high-temperature water heaters with outlet water temperatures as high as 120 degrees Celsius, pentafluoropropane is the mainstream refrigerant choice. Pentafluoropropane refrigerant is a colorless, transparent liquid with excellent fluidity and moderate volatility. It is chemically stable under normal temperature and pressure conditions and has a boiling point of 15.14 degrees Celsius.

[0003] When the operating temperature is below the boiling point of pentafluoropropane refrigerant, pentafluoropropane refrigerant is in a liquid state. At this time, the system pressure of the heat pump unit is at a low level. If the unit is started directly at this time, the liquid refrigerant will remain, making it difficult to heat the refrigerant in time, resulting in difficulty in raising the temperature and pressure. The compressor is prone to liquid slugging or low pressure alarm when it is started, which will seriously affect the normal operation of the unit.

[0004] In summary, how to solve the problem of difficulty in starting up when pentafluoropropane refrigerant is in a liquid state is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0024] Preferably, the heating component further includes a gas-liquid separator, the inlet of which is connected to the refrigerant outlet of the heat exchanger, and the outlet of which is connected to the inlet of the compressor.

[0025] Preferably, the heat exchanger, the compressor, the gas-liquid separator, and the economizer are arranged sequentially along the width direction of the casing;

[0026] The condenser and the liquid receiver are arranged sequentially along the width of the housing;

[0027] Furthermore, the heat exchanger and the condenser are located near the first side of the casing, while the economizer and the liquid receiver are located near the second side of the casing.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The core of this application is to provide a high-temperature water heater that has a lower start-up failure rate compared to related products. Another core aspect of this application is to provide a high-temperature water heater system including the aforementioned high-temperature water heater.

[0045] This application provides a high-temperature water heater, including a casing 1, a condenser 2, a liquid receiver 3, and a heating component 4. The condenser 2 is used to heat the liquid to be heated by condensing a gaseous refrigerant. The liquid receiver 3 is used to contain and store the refrigerant. The heating component 4 receives low-temperature refrigerant and outputs high-temperature refrigerant. The condenser 2, liquid receiver 3, and heating component 4 are sequentially connected via inlet and outlet connections to form a circulation loop. The casing 1 has a first accommodating chamber 11 and a second accommodating chamber 12, with the first accommodating chamber 11 located at the top of the second accommodating chamber 12. The condenser 2 and the liquid receiver 3 are both located in the first accommodating chamber 11, and the heating component 4 is located in the second accommodating chamber 12. The height of the condenser 2 is higher than that of the liquid receiver 3.

[0046] refer to Figure 1 As explained, the housing 1 has a structure with upper and lower sides, that is, a shelf is provided at the middle of the height to divide its internal cavity into a first accommodating chamber 11 located at the top and a second accommodating chamber 12 located at the bottom.

[0047] To achieve heating, this high-temperature water heater is equipped with a circulation loop including a condenser 2, a liquid receiver 3, and a heating element 4. This loop guides the flow of refrigerant. After the gaseous refrigerant flows into the tube side of the condenser 2, it can heat the liquid to be heated flowing through the shell side of the condenser 2. The gaseous refrigerant is condensed by the condenser 2 and becomes liquid refrigerant, which then flows into the liquid receiver 3 for storage and is discharged into the heating element 4 when needed.

[0048] Since the condenser 2 and the liquid receiver 3 are both located in the first accommodating chamber 11, and the heating components 4 are both located in the second accommodating chamber 12, the liquid refrigerant flows from top to bottom into the heating components 4, while the gaseous refrigerant flows from bottom to top into the condenser 2. Furthermore, since the height of the condenser 2 is higher than that of the liquid receiver 3, the condensed liquid refrigerant in the condenser 2 can flow smoothly into the liquid receiver 3 due to its own gravity and / or the pressure difference within the system. Therefore, this high-temperature water heater does not require additional power equipment, which ensures the smooth flow of refrigerant in the circulation loop. Compared with related technologies, this high-temperature water heater has lower energy consumption, a significantly improved system start-up success rate, and is less prone to liquid slugging or low-pressure alarms, resulting in higher reliability and efficiency.

[0049] Based on the above embodiment, the liquid reservoir 3 has a liquid outlet 31, which is located at the bottom of the liquid reservoir 3.

[0050] refer to Figure 1 , Figure 2 and Figure 3 As explained, the liquid reservoir 3 has a liquid outlet 31 that penetrates its own shell wall. In order to ensure that the liquid refrigerant in the liquid reservoir 3 can be discharged smoothly, the liquid outlet 31 is located at the bottom of the liquid reservoir 3.

[0051] Based on the above embodiments, the liquid reservoir 3 has a liquid inlet located at the bottom of the liquid reservoir 3; and a liquid inlet pipe 32 is inserted into the liquid inlet, the liquid inlet pipe 32 extending vertically and inserted into the interior of the liquid reservoir 3, the pipe wall of the liquid inlet pipe 32 has a plurality of drain holes 321, and the plurality of drain holes 321 are arranged along the length direction of the liquid inlet pipe 32.

[0052] refer to Figure 1 , Figure 2 and Figure 3 As explained, the liquid receiver 3 has a liquid inlet that penetrates its own shell wall. To ensure smooth flow of liquid refrigerant into the liquid receiver 3, the liquid inlet is also located at the bottom of the liquid receiver 3, maximizing the height difference between the condenser 2 and the liquid receiver 3, thus improving the smoothness of liquid refrigerant flow into the liquid receiver 3. An inlet pipe 32 is inserted into the liquid inlet. The section of the inlet pipe 32 inserted into the liquid receiver 3 extends vertically, and three or more openings are made in the wall of this section. Figure 2With four or more drain holes 321 as shown, the liquid refrigerant is introduced into the storage chamber of the liquid reservoir 3 through the inlet pipe 32 and then flows into it through the drain holes 321. Since the drain holes 321 are arranged vertically, the liquid refrigerant can be quickly discharged into the liquid reservoir 3. And since the liquid reservoir 3 is set to be bottom inlet and outlet, it can play a buffering role.

[0053] Preferably, the volume of the liquid receiver 3 is 0.5-1 times the refrigerant charge of the circulating loop, in order to improve cost advantage.

[0054] Based on the above embodiment, the bottom arched cover 33 of the liquid reservoir 3 has an arched top that protrudes towards the bottom, and the liquid outlet 31 is located at the arched top of the arched cover 33.

[0055] refer to Figure 2 As explained, the arched cover 33 at the bottom of the liquid reservoir 3 is part of the shell that forms the internal liquid storage chamber. In order to discharge all the refrigerant stored in the liquid reservoir 3, the outlet 31 is opened at the arched top of the arched cover 33, and the arched top of the arched cover 33 protrudes downward.

[0056] It should be noted that the dome of the arched cover 33 can be located at the center of the liquid reservoir 3 or around the perimeter of the liquid reservoir 3, as long as it can meet the requirements for guiding the flow of refrigerant.

[0057] Based on the above embodiments, the heating component 4 includes a heat exchanger 41 and a compressor 42. The heat exchanger 41 has a refrigerant inlet, a refrigerant outlet, a heat exchange medium inlet, and a heat exchange medium outlet. The refrigerant inlet is connected to the outlet of the liquid receiver 3, and the refrigerant outlet is connected to the inlet of the compressor 42. The outlet of the compressor 42 is connected to the inlet of the condenser 2. The heat exchange medium inlet is used to connect to a liquid supply device to input the heat exchange medium into the heat exchanger 41, and the heat exchange medium outlet is used to discharge the heat exchange medium after exchanging heat with the refrigerant.

[0058] refer to Figure 1 and Figure 3As explained, the heating component 4 also includes a heat exchanger 41 and a compressor 42. The compressor 42, condenser 2, and liquid receiver 3 are sequentially connected, with the outlet of one component connected to the inlet of the next. Since this high-temperature water heater heats the refrigerant through the heat exchanger 41, preheating can be achieved simply by inputting hot water into the heat exchanger 41 using a water inlet device before the unit starts operating. The temperature range of the hot water input into the heat exchanger 41 can be 40-65 degrees Celsius. When the heat exchanger is working, the refrigerant passes through the heat exchanger... The inlet flows into the heat exchanger and exits through the refrigerant outlet. Hot water flows into the heat exchanger 41 through the heat exchange medium inlet and exchanges heat with the liquid refrigerant in the heat exchanger 41 before exiting through the heat exchange medium outlet. Since the height of the liquid receiver 3 is higher than that of the heat exchanger 41, the liquid refrigerant can flow into the heat exchanger 41 under the action of gravity. At this time, the hot water input into the heat exchanger 41 is preheated. After absorbing heat, the liquid refrigerant will quickly rise in temperature and pressure. When the unit start-up conditions of the high-temperature hot water machine are met, the unit is turned on to ensure normal operation of the unit and effectively prevent the compressor 42 from burning out.

[0059] Furthermore, it also includes a controller, a first temperature detector, a second temperature detector, a third temperature detector, and a fourth temperature detector. The first temperature detector is used to detect the temperature of the heat exchange liquid flowing into the shell side of the heat exchanger 41, the second temperature detector is used to detect the temperature of the heat exchange liquid flowing out of the shell side of the heat exchanger 41, the third temperature detector is used to detect the temperature of the heat exchange liquid flowing into the shell side of the condenser 2, and the fourth temperature detector is used to detect the temperature of the heat exchange liquid flowing out of the shell side of the condenser 2. The controller is connected to the first temperature detector, the second temperature detector, the third temperature detector, and the fourth temperature detector, the condenser 2, and the heating component 4. It is used to receive temperature data of the heat exchange liquid flowing into and out of the heat exchanger 41 and the heat exchange liquid flowing into and out of the condenser 2, and to control the condenser 2 and the heating component 4 to start.

[0060] Furthermore, the controller is used to determine the real-time saturation pressure of the refrigerant in the heat exchanger 41 based on the temperature data, and to control the compressor 42 to start when the saturation pressure is greater than 1.5 bar.

[0061] Based on the above embodiments, the heating component 4 also includes an economizer 43, which has a liquid refrigerant inlet, a liquid refrigerant outlet, a gaseous refrigerant outlet, and a liquid refrigerant replenishment port; the liquid refrigerant inlet is connected to the outlet of the liquid receiver 3; the liquid refrigerant outlet is connected to the refrigerant inlet of the heat exchanger 41; the gaseous refrigerant outlet is connected to the inlet of the compressor 42; and the liquid refrigerant replenishment port is connected to the liquid refrigerant outlet.

[0062] refer to Figure 1 and Figure 3To improve the heating capacity of the system, the high-temperature water heater is equipped with an economizer 43, which allows the refrigerant entering the heat exchanger 41 to better absorb heat. The receiver 3 is connected to the heat exchanger 41 through the economizer 43. During the circulation loop, the liquid refrigerant flowing out of the receiver 3 enters the economizer 43 through the liquid refrigerant inlet at the top. After processing, the economizer 43 discharges the heat-absorbing and evaporating gaseous refrigerant to the compressor 42 through its left gaseous refrigerant outlet, and discharges the subcooled liquid refrigerant to the heat exchanger 41 through its bottom liquid refrigerant outlet. The liquid refrigerant discharged from the economizer 43 through its liquid refrigerant outlet flows back into the economizer 43 through the liquid refrigerant replenishment port, so as to better absorb heat and improve the heating effect of the high-temperature water heater.

[0063] Based on the above embodiments, the heating component 4 also includes a gas-liquid separator 44, the inlet of which is connected to the refrigerant outlet of the heat exchanger 41, and the outlet of which is connected to the inlet of the compressor 42.

[0064] refer to Figure 1 and Figure 3 As explained, to prevent incompletely evaporated refrigerant from affecting the operation of compressor 42, the high-temperature water heater is also equipped with a gas-liquid separator 44. Heat exchanger 41 is connected to compressor 42 through gas-liquid separator 44. When the circulation loop is running, the refrigerant in heat exchanger 41 exchanges heat with the externally input high-heat medium and evaporates, then flows into gas-liquid separator 44. After gas phase refrigerant and liquid phase refrigerant are separated by gas-liquid separator 44, gas phase refrigerant is discharged to compressor 42 through its top outlet.

[0065] Based on the above embodiments, the heat exchanger 41, compressor 42, gas-liquid separator 44 and economizer 43 are arranged sequentially along the width direction of the casing 1; the condenser 2 and liquid receiver 3 are arranged sequentially along the width direction of the casing 1; and the heat exchanger 41 and condenser 2 are close to the first side of the casing 1, while the economizer 43 and liquid receiver 3 are close to the second side of the casing 1.

[0066] refer to Figure 3 As explained, the condenser 2 and liquid receiver 3 located at the top are arranged horizontally, with the condenser 2 on the left and the liquid receiver 3 on the right; the heat exchanger 41, compressor 42, gas-liquid separator 44 and economizer 43 located at the bottom are also arranged horizontally, with the heat exchanger 41 on the far left and the economizer 43 on the far right. With this arrangement, the layout of the high-temperature water heater is simple and reasonable.

[0067] Based on the above embodiments, it also includes a first throttle valve 5 and a second throttle valve 6. The first throttle valve 5 is located between the heat exchanger 41 and the economizer 43, and the second throttle valve 6 is located between the liquid refrigerant outlet and the liquid refrigerant replenishment port.

[0068] refer to Figure 3 As explained, the liquid refrigerant outlet of the economizer 43 is connected to branch pipe one and branch pipe two, that is, there are two branch pipes. Branch pipe one is connected to heat exchanger 41, and branch pipe two is connected to the liquid refrigerant replenishment port of the economizer 43 itself. Correspondingly, throttle valve one 5 is set on branch pipe one, and throttle valve two 6 is set on branch pipe two. When the system is running, part of the liquid refrigerant discharged from the economizer 43 flows to heat exchanger 41 after throttling, and the remaining part flows back to economizer 43 after throttling.

[0069] It should be noted that there are no restrictions on the type of throttle valve, as long as it meets the throttling function, such as... Figure 1 and Figure 3 The electronic expansion valve shown, or the thermal expansion valve, etc.

[0070] In addition to the high-temperature water heater described above, this application also provides a high-temperature water heater system that includes the high-temperature water heater disclosed in the above embodiments. The high-temperature water heater system includes the components that form a circulation loop in the high-temperature water heater described above, and the structure of the other parts of the high-temperature water heater system is described in the prior art, and will not be repeated here.
