Description

Technical Field

[0001] The utility model belongs to the technical field of air source heat pumps, and in particular relates to a heat storage device for an air source heat pump. Background Art

[0002] Air source heat pump technology uses ambient air as a heat source, absorbing heat from the air through a heat pump system for heating or hot water production. This technology has become a widely used heat supply method in commercial and educational buildings due to its environmental protection and energy efficiency. Especially in places such as schools that require a large amount of hot water and heating, air source heat pump systems show their unique value and application potential.

[0003] However, existing school hot water supply systems, especially those using traditional air source heat pumps, often face problems of low energy efficiency and unstable hot water supply. This is mainly because in traditional systems, hot water storage and supply often use a single water storage tank, and cold water and hot water are directly mixed in one container, resulting in serious heat energy loss and a rapid drop in hot water temperature, which cannot meet the hot water demand during peak hours.

[0004] In addition, since the water demand of schools varies significantly between peak and off-peak hours, traditional heat pump thermal storage devices lack flexibility and response speed in adjusting water temperature and water volume, and often cannot effectively adapt to such frequently changing demand patterns. This not only affects the daily operations of educational institutions, but also increases energy waste and operating costs. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An air source heat pump heat storage device comprises a bin, wherein the number of the bins is set to two, and the opening ends of the two bins are connected together, and an isolation piece is embedded between the opening ends of the two bins;

[0013] Furthermore, a sealing groove is provided on the outer side of the piston head, and a sealing ring is sleeved in the sealing groove;

[0014] A connecting seat is symmetrically arranged at the bottom of the receiving member.

[0015] Furthermore, a support member is connected below the storage body arranged at the bottom, a positioning groove is provided on the upper end surface of the support member, and support legs are symmetrically fixedly connected to the bottom of the support member.

[0016] Furthermore, a first through hole is symmetrically opened at the bottom of the bin body, both ends of the pipeline are respectively connected to the first through hole, and a three-way valve is connected to the middle of the pipeline;

[0017] A second through hole corresponding to the first through hole is formed through the bottom of the positioning groove.

[0018] Furthermore, the outer sides of the bin are connected with insulation covers;

[0019] A filling groove is provided on the side of the bin body, and a ball cover is fixedly connected to the outer side of the heat-insulating cover;

[0020] A heat insulator is filled between the ball cover and the filling groove;

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] In the utility model, the hot water and the cold water are effectively separated by introducing a double-storage structure and a partition in the middle, solving the problem of heat energy loss caused by the mixing of hot and cold water in the traditional single water storage tank. The layered plate and connecting pipe design in the partition not only enhance the structural stability of the tank, but also improve the efficiency and quality of heat storage by precisely controlling the water flow. This design enables the heat pump system to maintain efficient energy utilization under different water storage requirements, significantly improving the overall thermal efficiency and energy efficiency.

[0025] In the present invention, the precise control of the water flow channel between the two chambers is achieved through the sophisticated design of the connecting mechanism, including the coordinated work of the piston head, piston rod, receiving member and cylinder. This not only ensures that the two chambers can be effectively isolated or connected when needed, but also enhances the flexibility and responsiveness of the system under different operating conditions. In particular, the application of the sealing groove and sealing ring in the piston head design ensures that there will be no water leakage in the process of controlling the water flow, thereby maintaining the sealing and operating efficiency of the system.

[0026] In the utility model, the insulation cover and heat insulation design on the outside of the silo further reduce the loss of heat energy. The insulation filling between the insulation cover and the silo and the structural design of the ball cover and the threaded groove not only improve the insulation effect, but also facilitate the disassembly and assembly of the insulation cover, which is convenient for the daily maintenance and overhaul of the system. This comprehensive insulation measure significantly improves the heat retention capacity of the heat pump system, thereby optimizing energy consumption and operating costs.

[0055] The working principle of the utility model is:

[0056] When in use, the cylinder 45 is used to control the up and down movement of the receiving member 44, and the piston rod 42 cooperates to control the position of the piston head 41 in the connecting pipe 32. When the piston head 41 is above the drainage groove 321, the water stored in the two warehouse bodies 1 can flow through the drainage groove 321, and when the piston head 41 is below the drainage groove 321, the water between the two warehouse bodies 1 cannot flow.

[0057] In this way, when the water is replenished in the silo 1, the cold water replenished can be separated from the hot water stored in the silo 1, thereby avoiding the contact between the cold water and the hot water, which causes the temperature of the hot water to drop;

[0058] In the specific operation process, when the water stored in the upper bin body 1 reaches a predetermined temperature, under the control of the connecting mechanism 4, the water in the upper bin body 1 enters the connecting pipe 32 through the drainage groove 321 and flows into the bin body 1 arranged at the bottom;

[0059] When replenishing water, cold water is added into the warehouse body 1 arranged above through the pipeline 5.

The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
