Description

Technical Field

[0001] The present application relates to the technical field of heat pump air conditioners, and in particular to a heating structure and a heating method for an air supply circuit of an injection enthalpy increase system. Background Art

[0002] Jet reheating is a technology used to improve the winter heating performance of heat pump air conditioners or other heat pump equipment. Its core lies in adding a heat exchange system to separate part of the intermediate pressure gaseous refrigerant, and compressing it through a jet reheating compressor with an auxiliary air intake, thereby enhancing the heating effect. Introducing jet reheating technology on traditional heat pump air conditioner compressors can not only achieve a strong heating effect in low temperature environments, but also does not require the use of electric auxiliary heating, thereby reducing users' power consumption and achieving energy conservation and emission reduction.

[0003] At present, the thermal energy utilization efficiency of the jet enthalpy increase system still needs to be improved, especially in ultra-low temperature environments, where the heating capacity is subject to certain limitations. Therefore, the waste heat in the system will be recycled in related technologies, such as installing a water jacket outside the compressor. In order to ensure that the liquid heat carrier does not freeze in a low-temperature environment, heat transfer oil is injected into the water jacket. After the heat transfer oil absorbs the temperature of the compressor, the high-temperature heat transfer oil is transported to the refrigerant heater through a circulating pump, and the high-temperature heat transfer oil heats the low-temperature gas-liquid mixed refrigerant.

[0004] However, the gas compression structure inside some compressors is located in an eccentric position of the compressor, which causes the waste heat generated by the compressor during the compression process to be concentrated in a certain area of ​​the compressor, rather than distributed around the entire periphery of the compressor. If a heat exchange device is directly installed on the compressor outer shell, the heat transfer medium will flow along the heat exchange device from the waste heat concentration area to the non-waste heat concentration area, causing a certain amount of heat loss, resulting in low thermal energy utilization efficiency. Summary of the invention

[0005] In order to improve the thermal energy utilization efficiency of the jet enthalpy increase system, on the one hand, the present application provides a heating structure for the air supplement loop of the jet enthalpy increase system.

[0006] The following technical solutions are adopted:

[0045] The following is combined with Figure 1-6 This application is described in further detail.

[0046] Embodiment 1:

[0047] Referring to Figure 1, an embodiment of the present application provides a heating structure for an air supply circuit of an injection reheating system, including a compressor 1 and a heating device 2. The compressor 1 includes a compressor cylinder 11, an air supply interface 12 and an exhaust interface 13 connected to the compressor cylinder 11, and a waste heat concentration area is arranged on the periphery of the compressor cylinder 11. The heating device 2 includes a heat storage shell 21, and the heat storage shell 21 is specifically configured as a hollow arc-shaped plate; an air intake port and an air discharge port are provided on the heat storage shell 21, and the air discharge port is located above the air intake port. An air discharge port 23 is fixed to the air discharge port on the heat storage shell 21, and an air intake port 22 is fixed to the air intake port. The air discharge port 23 is connected to the air supply port 12 through a flexible pipe or a rigid pipe (not shown in the figure).

[0048] The heat storage shell 21 is made of a heat storage material with good thermal conductivity, which can effectively prevent the rapid loss of heat. In the present embodiment, the heat storage shell 21 is made of stainless steel or copper. The air intake interface 22 and the air discharge interface 23 are used to introduce and discharge the refrigerant, respectively. Through the heat exchange in the heat storage shell 21, the refrigerant reaches a suitable intermediate pressure, and the enthalpy value of the refrigerant in the air supply circuit is increased, thereby reducing the energy consumption of the system and increasing the heating capacity of the system. The air discharge port is located above the air intake port, so that the gaseous refrigerant can use the buoyancy effect to enter the air supply interface 12 of the compressor 1 during the heating process to reduce the pressure loss.

[0049] The heat storage shell 21 covers the waste heat concentration area, and the inner wall of the heat storage shell 21 is fixedly connected to the outer wall of the compressor cylinder 11. The periphery of the compressor cylinder 11 is provided with a waste heat concentration area, which is a high temperature area generated during the operation of the compressor 1. Through the effective coverage of the heat storage shell 21, the waste heat generated by the compressor 1 can be utilized to the maximum extent, thereby improving the utilization efficiency of heat energy.

[0050] The implementation principle of this embodiment is: the heating device 2 precisely covers the waste heat concentration area of ​​the compressor 1, avoiding the heat loss caused by the traditional heat exchange device when the heat transfer medium passes through the waste heat concentration area to the non-waste heat concentration area during the flow process. As a result, the thermal energy utilization efficiency of the jet enthalpy increase system is significantly improved, so that it can maintain efficient heating performance even in ultra-low temperature environments, reduce the energy consumption of users, and achieve the goal of energy saving and emission reduction.

[0051] Embodiment 2:

In this embodiment, three partitions 28 are specifically provided.

[0053] After entering the heat storage shell 21, the low-temperature refrigerant can flow along the heat exchange flow channel 211. The guided refrigerant flows more evenly and continuously in the heat storage shell 21, achieving uniform heat absorption. In other embodiments, the number of baffles 28 can be adjusted to change the total length of the flow channel, the arrangement of the baffles 28 can be adjusted to change the distribution of the flow channel, and the structure of the baffles 28 can be optimized, such as wave shape, sawtooth shape, etc., to increase the heat exchange area and enhance the turbulence effect of the refrigerant in the cavity, thereby optimizing the heat transfer characteristics to meet the temperature required by the intermediate pressure.

[0054] The implementation principle of this embodiment is: by arranging a plurality of staggered partitions 28 in the heat storage shell 21, a heat exchange flow channel 211 is formed in the heat storage shell 21, which can significantly increase the heat exchange area and improve the heat exchange efficiency. In this way, the heat energy utilization efficiency of the jet enthalpy increase system is further improved, so that a higher heating performance can be maintained even in an ultra-low temperature environment, reducing the energy consumption of users and achieving better energy saving and emission reduction effects.

The heat storage shell 21 can be filled with heat transfer oil or other high-efficiency heat storage medium. According to the temperature requirement of the intermediate pressure of the refrigerant, a heat storage medium with suitable physical properties can be selected and filled into the heating device 2 to absorb and store the waste heat of the compressor 1.

In actual applications, it is also possible to design heat exchange tubes 29 of different lengths, inner diameters and numbers in the heating device 2.
