Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a multifunctional refrigeration system. Background Art

[0002] The refrigeration system uses a compressor to compress the refrigerant and guide the refrigerant through corresponding pipes (such as copper pipes) into the condenser and evaporator for heat exchange.

[0003] For example, the heat pump system for making hot water uses the principle that the high-temperature and high-pressure gaseous refrigerant with a large amount of heat in the condenser of the refrigerant circulation system needs to dissipate heat and liquefy. The condenser is placed in a heat exchange terminal (such as a water storage container) to absorb heat from water at room temperature to obtain hot water, and then the hot water is transported through pipelines to places where it is needed, such as domestic hot water for bathing and washing dishes. Conversely, when there is a demand for cold water, the evaporator is placed in a heat exchange terminal (such as a water storage container) to use the heat in the room temperature or high temperature water to vaporize the low-temperature and low-pressure liquid refrigerant. In this process, the refrigerant absorbs the heat in the water to obtain cold water, and then the cold water is transported through pipelines to places where it is needed, such as equipment cooling water.

[0004] However, in the technology of related refrigeration systems, the refrigeration system mainly uses the heat exchange principle of the condenser or evaporator to heat or cool. This process can only achieve cooling or heating alone, which will cause some energy waste when cooling or heating alone. Utility Model Content

[0046] In order to facilitate the understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.

[0047] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] Combine the following Figures 1 to 5It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0050] See also Figures 1 to 5 An embodiment of the utility model provides a multifunctional refrigeration system, which includes a compressor 100, an evaporator 200, a condenser 300, an expansion valve 400, a first pump 500, a second pump 600, a first electromagnetic reversing valve 700 and a second electromagnetic reversing valve 800.

[0051] The compressor 100 is fixedly disposed on the fixed base 900 , and the compressor 100 can be used to compress the refrigerant.

[0052] The evaporator 200 includes an evaporation inlet 210 and an evaporation outlet 220;

[0053] The condenser 300 includes a condensation inlet 310 and a condensation outlet 320;

[0054] The expansion valve 400 connects the evaporator 200 and the condenser 300;

[0055] The compressor 100, the condenser 300, the expansion valve 400 and the evaporator 200 are connected in series in sequence, and the evaporator 200 is connected to the compressor 100 to form a heat exchange circulation loop of the refrigerant. That is, the compressor 100 presses the refrigerant into the condenser 300, and the refrigerant is converted from gas to liquid and releases heat to achieve heating; after the liquid refrigerant passes through the expansion valve 400, it is converted from liquid to gas in the evaporator 200 to absorb heat to achieve cooling.

[0056] In addition, the first pump 500 has a first pump inlet 510 and a first pump outlet 520 , and the first pump 500 can pump out the first heat exchange medium.

[0057] The second pump 600 has a second pump inlet 610 and a second pump outlet 620 , and the second pump 600 can pump out the second heat exchange medium.

[0058] The first solenoid reversing valve 700 includes a first input end 710, a second input end 720, a first output end 730 and a second output end 740; the first input end 710 is connected to the first pump outlet 520, the first output end 730 is connected to the evaporation inlet 210, the second input end 720 is connected to the second pump outlet 620, and the second output end 740 is connected to the condensation inlet 310.

[0059] The second electromagnetic reversing valve 800 includes a third input terminal 810, a fourth input terminal 820, a third output terminal 830 and a fourth output terminal 840; the third input terminal 810 is connected to the evaporation outlet 220, the fourth input terminal 820 is connected to the condensation outlet 320, and the third output terminal 830 can be connected to the first heat exchange terminal 910 outside, and the first heat exchange terminal 910 is connected to the inlet of the first pump 500 to form a heat exchange circulation loop of the first heat exchange medium.

[0060] The fourth output terminal 840 can be connected to the second heat exchange terminal 920 outside, and the second heat exchange terminal 920 is connected to the inlet of the second pump 600 to form a heat exchange circulation loop of the second heat exchange medium.

[0061] In order to reduce the space required by the multifunctional refrigeration system and facilitate the arrangement of various components, high pressure and corrosion resistant hoses are used between the various components. For example, the first input end 710 of the first electromagnetic reversing valve 700 is connected to the first pump outlet 520 using a rubber hose; the third input end 810 of the second electromagnetic reversing valve 800 is also connected to the evaporation outlet 220 using a rubber hose.

[0062] Specifically, the first heat exchange terminal 910 may be an indoor unit of the air conditioner, and the second heat exchange terminal 920 may be an outdoor unit of the air conditioner. When the indoor unit needs to be cooled, the first heat exchange medium (the first heat exchange medium may be water) pumped out by the first pump 500 may flow through the evaporator 200 after passing through the first electromagnetic reversing valve 700, and the heat of the first heat exchange medium is absorbed by the evaporator 200. After passing through the second electromagnetic reversing valve 800, the first heat exchange medium flows through the first heat exchange terminal 910 (i.e., the indoor unit of the air conditioner) and returns to the first pump 500, completing the heat exchange circulation loop of the first heat exchange medium. By maintaining the flow of the first heat exchange medium, the first heat exchange terminal 910 (i.e., the indoor unit of the air conditioner) can achieve cooling.

[0063] At this time, the second heat exchange terminal 920 can be used to heat domestic water, that is, the second heat exchange medium (the second heat exchange medium can also be water) pumped out by the second pump 600 can flow through the condenser 300 after passing through the second electromagnetic reversing valve 800. The second heat exchange medium is heated by the heat released by the condenser 300. After passing through the second electromagnetic reversing valve 800, the second heat exchange medium flows through the second heat exchange terminal 920 (i.e., the air conditioner outdoor unit) and returns to the second pump 600, completing the heat exchange cycle of the second heat exchange medium. Maintaining the flow of the second heat exchange medium can enable the second heat exchange terminal 920 (i.e., the air conditioner outdoor unit) to achieve heating.

[0064] It can be understood that the multifunctional refrigeration system provided by the embodiment of the utility model can constitute a heat exchange circulation loop of the first heat exchange medium by connecting the first pump 500, the first electromagnetic reversing valve 700, the evaporator 200, the second electromagnetic reversing valve 800 and the first heat exchange terminal 910 in series in sequence, and the first heat exchange terminal 910 is connected to the first pump inlet 510; the second pump 600, the first electromagnetic reversing valve 700, the condenser 300, the second electromagnetic reversing valve 800 and the second heat exchange terminal 920 are connected in series in sequence, and the second heat exchange terminal 920 is connected to the second pump inlet 610, to constitute a heat exchange circulation loop of the second heat exchange medium.

[0065] When the first pump 500 pumps out the first heat exchange medium, the first heat exchange medium flows through the first electromagnetic reversing valve 700, the evaporator 200, the second electromagnetic reversing valve 800 and the first heat exchange terminal 910 in sequence, and the first heat exchange terminal 910 can achieve cooling; at the same time, the second pump 600 pumps out the second heat exchange medium, and the second heat exchange medium flows through the first electromagnetic reversing valve 700, the condenser 300, the second electromagnetic reversing valve 800 and the second heat exchange terminal 920 in sequence, and the second heat exchange terminal 920 can achieve heating.

[0066] During this process, the refrigeration system can perform cooling and heating simultaneously, which can avoid energy waste and save costs.

[0067] In some embodiments of the present invention, the first solenoid reversing valve 700 and the second solenoid reversing valve 800 both have a first state and a second state, and the first solenoid reversing valve 700 and the second solenoid reversing valve 800 can both be two-way four-way solenoid valves.

[0068] In the first state, the first input end 710 of the first electromagnetic reversing valve 700 is connected to the first output end 730, and the second input end 720 of the first electromagnetic reversing valve 700 is connected to the second output end 740;

[0069] The third input end 810 of the second electromagnetic reversing valve 800 is connected to the third output end 830, and the fourth input end 820 of the second electromagnetic reversing valve 800 is connected to the fourth output end 840. Figure 4 The arrow directions of the first electromagnetic reversing valve 700 and the second electromagnetic reversing valve 800 are in a "parallel" state.

[0070] In the second state, the first input end 710 of the first electromagnetic reversing valve 700 is connected to the second output end 740, and the second input end 720 of the first electromagnetic reversing valve 700 is connected to the first output end 730;

[0071] The third input end 810 of the second electromagnetic reversing valve 800 is connected to the fourth output end 840, and the fourth input end 820 of the second electromagnetic reversing valve 800 is connected to the third output end 830. Figure 4The arrow directions of the first electromagnetic reversing valve 700 and the second electromagnetic reversing valve 800 are in a "cross" state.

[0072] Specifically, when indoor heating is required, the first electromagnetic reversing valve 700 and the second electromagnetic reversing valve 800 are in the second state.

[0073] At this time, the first heat exchange terminal 910 is also the indoor unit of the air conditioner, and the second heat exchange terminal 920 is also the outdoor unit of the air conditioner. The first heat exchange medium (the first heat exchange medium may be water) pumped out by the first pump 500 can flow through the condenser 300 after being reversed by the first electromagnetic reversing valve 700. The first heat exchange medium is heated by the heat released by the condenser 300. After being reversed by the second electromagnetic reversing valve 800, the first heat exchange medium flows through the first heat exchange terminal 910 (i.e. the indoor unit of the air conditioner) and returns to the first pump 500, completing the heat exchange circulation loop of the first heat exchange medium. Keeping the flow of the first heat exchange medium can enable the first heat exchange terminal 910 (i.e. the indoor unit of the air conditioner) to achieve heating.

[0074] At the same time, the second heat exchange medium pumped out by the second pump 600 (the second heat exchange medium can also be water) can flow through the evaporator 200 after being reversed by the second electromagnetic reversing valve 800. The heat of the second heat exchange medium is absorbed by the evaporator 200. After being reversed by the second electromagnetic reversing valve 800, the second heat exchange medium flows through the second heat exchange terminal 920 (i.e., the air conditioner outdoor unit) and returns to the second pump 600, completing the heat exchange cycle of the second heat exchange medium. Maintaining the flow of the second heat exchange medium can enable the second heat exchange terminal 920 (i.e., the air conditioner outdoor unit) to achieve cooling and exchange heat with the outdoor environment.

[0075] It can be seen that the multifunctional refrigeration system provided by the utility model is provided with a first electromagnetic reversing valve 700 and a second electromagnetic reversing valve 800 with a first state and a second state. When adjusting the cooling and heating demands, there is no need to swap the positions of the first heat exchange terminal 910 (i.e., the air-conditioning indoor unit) and the second heat exchange terminal 920 (i.e., the air-conditioning outdoor unit). It is only necessary to switch the states of the first electromagnetic reversing valve 700 and the second electromagnetic reversing valve 800. The operation is simple and can meet the application places with different cooling and heating demands.

[0076] Combination Figure 5 In some embodiments of the present invention, a plurality of first heat exchange terminals 910 may be provided, and each first heat exchange terminal 910 may be arranged in parallel to meet multiple application sites. For example, when the first heat exchange terminal 910 is an air conditioner indoor unit, one application site (e.g., room) may be provided with one air conditioner indoor unit.

[0077] A plurality of second heat exchange terminals 920 may also be provided, and each second heat exchange terminal 920 may be arranged in parallel to meet multiple application sites. For example, when the second heat exchange terminal 920 is an air conditioner outdoor unit, one application site (e.g., an external window fixing position) may be provided with one air conditioner indoor unit. In this way, the multifunctional refrigeration system may be configured in a diversified manner according to user needs.

[0078] See also Figures 1 to 3 In some embodiments of the utility model, the condenser 300, the expansion valve 400 and the evaporator 200 can all be arranged on the compressor 100 and form an integrated structure with the compressor 100, which can save the installation space required for the multifunctional refrigeration system, thereby saving installation costs; and the condenser 300, the expansion valve 400 and the evaporator 200 are closer to each other, which can shorten the length of the connecting conduit and prevent the dangers caused by the lengthy conduit (such as leakage).

[0079] See also Figures 1 to 4 In some embodiments of the present invention, in order to improve the stability of the multifunctional refrigeration system and further save the installation space required for it, the first pump 500 and the second pump 600 are arranged side by side on a fixed base 900.

[0080] Of course, the multifunctional refrigeration system is also provided with a shell 930, and a portable part 931 is provided on the shell 930, so as to prevent the refrigeration system from being contaminated and facilitate extraction.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
