Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an air conditioner capable of quickly preheating in a low-temperature environment. Background Art

[0002] With the development of society, environmental pollution and energy crisis have become the top threats to human survival. How to solve this problem has become a topic of great concern to all mankind. Against this background, green buildings with environmental protection and energy saving as their main characteristics and corresponding air-conditioning systems came into being.

[0003] A heat pipe is a heat transfer element with high thermal conductivity. It transfers heat by evaporating and condensing the working fluid in a fully enclosed vacuum tube shell. Due to phase change heat transfer, the thermal resistance inside the heat pipe is very small. It has a series of advantages such as extremely high thermal conductivity, good isothermal properties, and rapid startup. The heat exchange between the cold and hot fluids is carried out outside the tube, which can easily enhance heat transfer. Therefore, the development of heat pipe-type air-conditioning units with high energy efficiency and reliable operation based on the principle of heat pipes is the development trend of computer room air conditioners in the future.

[0004] In view of this, the heat pipe air-conditioning system is a technical innovation direction with broad technical prospects, and related technical creation results have also appeared in China. For example, the patent technology with publication number CN221098862U owned by the applicant proposes a technical innovation of a heat pipe dual-cold source air-conditioning system, which saves energy consumption. However, there is a problem of slow start-up when heating in a low-temperature environment, which still leads to a large amount of energy consumption. This is because the oil inside the pipe will be frozen in a low-temperature environment.

[0005] Therefore, an air conditioner with rapid preheating in a low temperature environment is now proposed to solve the above problems. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an air conditioner that can save a lot of energy and can quickly start and preheat in a low-temperature environment.

[0007] The purpose of the utility model is achieved by the following technical solutions:

[0008] According to an embodiment of the present disclosure, an air conditioner for rapid preheating in a low-temperature environment is provided, comprising a housing, wherein an air conditioning system, a heat pipe system, a water pump system, a condenser, and a plate heat exchanger are arranged in the housing;

[0009] The air conditioning system, heat pipe system and water pump system share a plate heat exchanger; the plate heat exchanger is provided with internally connected heat pipe inlets and heat pipe outlets, internally connected air conditioning inlets and air conditioning outlets, and internally connected water pump inlets and water pump outlets;

[0010] The air conditioning system comprises a compressor, the compressor is connected to a condenser via a high-pressure pipe, the condenser is connected to an air conditioning inlet of a plate heat exchanger via a throttle valve, and the air conditioning outlet of the plate heat exchanger is connected to the compressor via a low-pressure pipe;

[0011] The heat pipe system includes a heat inlet pipe and a heat outlet pipe; the heat inlet pipe is connected to the heat pipe inlet of the plate heat exchanger, the heat pipe outlet of the plate heat exchanger is connected to the heat outlet pipe, and the heat outlet pipe is connected to the condenser;

[0012] The water pump system includes a water pump; the water pump is connected to a water inlet pipe, which is connected to a water supply source outside the shell; the water pump is connected to a water pump inlet of a plate heat exchanger through a drain pipe, the water pump outlet of the plate heat exchanger is connected to the drain pipe, and the drain pipe leads to the outside of the shell.

[0013] As a preferred solution, the air conditioning system and the heat pipe system share a condenser.

[0014] As a preferred solution, an electric ball valve is installed on the heat inlet pipe.

[0015] As a preferred solution, the heat pipe system further includes a reflux pipe, one end of which is connected to the condenser, and the other end of which is connected to the heat outlet pipe.

[0018] In summary, compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. By making the air conditioning system, heat pipe system and water pump system share a plate heat exchanger without interfering with each other, a lot of energy consumption can be saved. Depending on the actual situation, 20% to 30% of energy consumption can be saved;

[0020] 2. When the outdoor temperature is low and the liquid in the pipe is frozen, the heat pipe system is operated to provide heat to the plate heat exchanger and thaw and preheat the liquid inside the plate heat exchanger. The liquid inside the plate heat exchanger vaporizes, thereby lowering the environment outside the plate heat exchanger. The fan then blows the cold air outside the plate heat exchanger outward to achieve a cooling effect.

[0021] 3. In the present application, after the heat pipe system preheats the liquid inside the plate heat exchanger, the liquid circulates between the plate heat exchanger, the condenser and the compressor, which can have a good lubrication effect on the pipeline and facilitate the refrigeration function.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Example 1: Figures 1 to 5 As shown, an air conditioner with rapid preheating in a low-temperature environment comprises a shell 1 , in which an air conditioning system, a heat pipe system, a water pump system, a condenser 5 , and a plate heat exchanger 6 are arranged.

[0037] The air conditioning system, heat pipe system and water pump system share a plate heat exchanger 6; the plate heat exchanger 6 is provided with an internally connected heat pipe inlet 61 and a heat pipe outlet 62, an internally connected air conditioning inlet 63 and an air conditioning outlet 64, and an internally connected water pump inlet 65 and a water pump outlet 66.

[0038] The air conditioning system includes a compressor 21, which is connected to the condenser 5 through a high-pressure pipe 22. The condenser 5 is connected to the air conditioning inlet 63 of the plate heat exchanger 6 through a throttle valve 22, and the air conditioning outlet 64 of the plate heat exchanger 6 is connected to the compressor 21 through a low-pressure pipe 23.

[0039] In this embodiment, the specific conditions of the air conditioning system during operation are as follows:

[0040] When the refrigeration function is needed, the compressor produces high-temperature and high-pressure steam, which enters the condenser for condensation to obtain high-pressure liquid. The high-pressure liquid comes out of the condenser and passes through the throttle valve to obtain low-temperature and low-pressure wet steam. The low-temperature and low-pressure wet steam enters the plate heat exchanger from the air-conditioning inlet. At this time, the low-temperature and low-pressure wet steam of the plate heat exchanger will emit cold gas, and then the fan will blow the cold air outward to achieve the refrigeration effect. After that, the steam inside the plate heat exchanger will become hot to obtain low-pressure steam, and the low-pressure steam will enter the compressor again, thus realizing the cycle.

[0041] The heat pipe system includes a heat inlet pipe 31 and a heat outlet pipe 32 ; the heat inlet pipe 31 is connected to the heat pipe inlet 61 of the plate heat exchanger 6 , the heat pipe outlet 62 of the plate evaporator 6 is connected to the heat outlet pipe 32 , and the heat outlet pipe 32 is connected to the condenser 5 .

[0042] The water pump system includes a water pump 41; the water pump 41 is connected to a water inlet pipe 42, and the water inlet pipe 42 is connected to a water supply source (not shown) outside the shell 1; the water pump 41 is connected to a water pump inlet 65 of the plate heat exchanger 6 through a drain pipe 43, and the water pump outlet 66 of the plate heat exchanger 6 is connected to the drain pipe 43, and the drain pipe 43 leads to the outside of the shell 1.

[0043] Specifically, the air conditioning system and the heat pipe system share a condenser 5 .

[0044] Specifically, an electric ball valve 34 is installed on the heat inlet pipe 31 .

[0045] Specifically, the heat pipe system further includes a reflux pipe 33 , one end of which is connected to the condenser 5 , and the other end of which is connected to the heat outlet pipe 32 .

[0046] In this embodiment, the specific conditions of the heat pipe system during operation are as follows:

[0047] When the refrigeration function needs to be realized in a low-temperature environment, the electric ball valve 34 is confirmed to be in an open state, and the heat pipe system is operated. The heat pipe system provides heat to the plate heat exchanger 6 and thaws and preheats the liquid inside the plate heat exchanger 6 (the liquid in the pipe is in a frozen state in a low-temperature environment). At this time, it is divided into the following two situations according to the different ambient temperatures:

[0048] Case 1: If the heat provided by the heat pipe can meet the heat dissipation requirements, the liquid inside the plate heat exchanger 6 can be vaporized without starting the compressor, thereby lowering the environment outside the plate heat exchanger, and then the fan blows the cold air outside the plate heat exchanger outward to achieve a cooling effect;

[0049] Case 2: If the heat provided by the heat pipe is not enough to meet the heat dissipation requirements, the compressor needs to be started and the air conditioning system needs to be operated to achieve refrigeration. At this time, since the heat pipe system has preheated the liquid inside the plate heat exchanger, the liquid circulates between the plate heat exchanger 6, the condenser 5 and the compressor 21, which can have a good lubrication effect on the pipeline and facilitate the refrigeration function.

[0050] Specifically, a fan 8 is disposed in the housing 1 .

[0051] Specifically, in the plate heat exchanger 6 , the heat pipe inlet 61 and the heat pipe outlet 62 are diagonally distributed, and the air conditioning inlet 63 and the air conditioning outlet 64 are diagonally distributed.

[0052] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
