Description

Technical Field

[0001] A deflection-flow type thermal storage and pressure-boosting air valve is disclosed. This utility model belongs to the field of valve technology and specifically relates to a deflection-flow type thermal storage and pressure-boosting air valve. Background Technology

[0002] When air-source heat pumps, air-source heat pumps, and air conditioners are operating, starting them in low ambient temperatures presents numerous challenges. Due to the low temperature, the return air temperature and low pressure of the air-source refrigerant system are too low, preventing the system from quickly reaching its normal operating pressure. Taking air-source heat pump grain dryers as an example, during cold seasons, the low return air temperature and low pressure of the refrigerant system lead to a significant decrease in drying efficiency and prolonged grain drying time, increasing production costs and potentially affecting grain quality. Similarly, slow start-up at low temperatures is a common problem in air conditioning and air-source heat pump systems, impacting the user experience.

[0003] The current solution mainly involves adding electric heating. While this method is effective in increasing system pressure, it has significant drawbacks. Firstly, electric heating consumes a huge amount of energy, significantly increasing the operating costs of the equipment. Taking large-scale air-source heat pump dryers as an example, the electricity consumed by electric heating accounts for a considerable proportion of the total energy consumption throughout the drying cycle, which is a heavy economic burden for companies and users who use such equipment long-term. Secondly, the use of electric heating does not align with current energy conservation and environmental protection principles. In the context of global advocacy for sustainable development, this high-energy-consuming solution is increasingly unable to meet market demands and has certain limitations in practical applications. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a deflection-type thermal storage and pressure-boosting air valve. This allows equipment such as air-source grain dryers, air-source heat pumps, and air conditioners to start up quickly at low ambient temperatures without the need for electric heating, effectively reducing energy consumption. Furthermore, this air valve should also possess a simple structure, be easy to install and maintain, to improve its feasibility and versatility in practical applications.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A deflection-type thermal storage and pressure boosting air valve includes a condenser. A valve body mounting frame for mounting a valve body is installed on the side of the condenser. A second valve body is installed inside the valve body mounting frame. A first valve body is slidably installed inside the valve body mounting frame between the second valve body and the condenser. Both the first and second valve bodies have openings for ventilation. The openings on the second valve body are completely offset from the openings on the first valve body.

[0007] As a preferred embodiment of this utility model, the distance between the valve body mounting frame and the condenser is set to be less than 5mm.

[0008] As a preferred embodiment of this utility model, a gap is provided between the openings, the width of the gap is greater than the width of the opening, and the valve body is slidably disposed up and down inside the valve body mounting frame.

[0009] As a preferred embodiment of this utility model, the thickness of both valve body one and valve body two is set to 4mm.

[0010] Compared with existing technologies, the beneficial effects of this utility model are: the deflection-flow heat storage and pressure-boosting air valve increases the return gas pressure during startup at low temperatures through deflection-flow heat storage, enabling the equipment to quickly reach normal operating pressure, avoiding the high energy consumption problem caused by electric heating, and reducing operating costs. Taking an air-source grain dryer as an example, after using this air valve, no electric heating is required during startup in low-temperature environments, and the refrigerant system can reach normal operating pressure in a relatively short time.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution:

[0018] A deflection-type thermal storage and pressure boosting air valve includes a condenser 1. A valve body mounting frame 2 is installed on the side of the condenser 1 for mounting the valve body. The mounting frame 2 supports and fixes the valve body, ensuring that the valve body can be stably installed on the condenser 1 and guaranteeing the relative positional accuracy between the valve body and the condenser 1, laying the foundation for subsequent efficient heat exchange and airflow control. A second valve body 4 is installed inside the valve body mounting frame 2. A first valve body 3 is slidably installed inside the valve body mounting frame 2 between the second valve body 4 and the condenser 1. Both the first valve body 3 and the second valve body 4 have openings 5 ​​for ventilation. The openings 5 ​​on the second valve body 4 and the first valve body 3 can be completely offset. This sliding installation design allows the first valve body 3 to move flexibly within the valve body mounting frame 2, thereby achieving precise control of the ventilation volume. By controlling the overlap of the openings 5 ​​on the first valve body 3 and the second valve body 4, the intake air can be effectively regulated, thereby achieving the purpose of deflection-type thermal storage and pressure boosting.

[0019] The distance between the valve body mounting frame 2 and the condenser 1 is set to be less than 5mm. This distance allows the air valve to more efficiently deflect the airflow into the condenser and store heat. If the distance is too large, some heat will be lost during transmission, reducing the effect of deflection and heat storage. If the distance is too small, it may affect the installation and normal sliding of the valve body. After extensive experiments and practical application verification, a distance of less than 5mm can maximize the pressure boosting effect on the refrigerant system while ensuring the normal operation of the valve body.

[0020] A gap 6 is provided between the openings 5, and the width of the gap 6 is greater than the width of the opening. The valve body 3 is installed inside the valve body mounting frame 2 and slides up and down. This structural design is conducive to precise control of ventilation volume. The width of the gap 6 is greater than the width of the opening 5, which allows for more flexible adjustment of the overlapping area of ​​the openings 5 ​​during the sliding process of the valve body 3, thereby achieving fine adjustment of the air intake. Compared with other sliding methods, the up and down sliding method of the valve body 3 has the advantages of simple structure and convenient operation, and can better adapt to different working environments and needs.

[0021] The thickness of both valve body 3 and valve body 4 is set to 4mm, which ensures that the overall structure of the air valve is thin and light. The thin and light structure not only reduces the space occupied and makes it easy to install in various air source heat pumps, but also does not affect its functions of deflection heat storage and pressure regulation. At the same time, the thinner valve body also helps to reduce material costs and improve production efficiency.

[0022] During actual installation, the valve body mounting frame should be tightly installed on the side of the condenser. Use appropriate installation tools and fasteners to ensure that the distance between the two is less than 5mm and that the installation is firm without any loosening or displacement. The valve body 3 can slide up and down within the valve body mounting frame 2. To ensure smooth sliding, an appropriate amount of lubricant can be applied to the contact surface between the valve body 3 and the valve body mounting frame 2 before installation.

[0023] When the equipment is in the low-temperature start-up phase and the refrigerant system pressure needs to be increased, the valve body 3 is slid to be completely offset from the opening 5 of the valve body 4 by an external control device such as an electric push rod or a manual crank. At this time, the air is deflected from the top, and the heat below cannot be dissipated. The refrigerant system pressure will continue to rise until it reaches the normal operating pressure. During this process, the pressure change of the refrigerant system can be monitored in real time by a pressure sensor so that the position of valve body 1 can be adjusted in time.

[0024] Once the system pressure reaches normal, the external control device can be operated again according to actual needs. Slide valve 3 to make the openings 5 ​​of valve body 1 and valve body 2 overlap, adjust the ventilation volume, and ensure the normal operation of the equipment. During the adjustment process, pay attention to the operating status of the equipment to ensure that the adjustment of the ventilation volume will not have a negative impact on the normal operation of the equipment.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
