Description

TECHNICAL FIELD

[0001] The utility model relates to air energy system technical field especially is related to a kind of intelligent variable frequency circulating liquid supplementing multifunctional pump. BACKGROUND

[0002] Air energy refers to the low-grade heat energy contained in air. However, according to the second law of thermodynamics, heat cannot be transferred from a low-temperature heat source to a high-temperature heat source without causing other changes. Therefore, air cannot be utilized without consuming external energy. A heat pump can absorb heat from air and transfer it to a high-temperature object or environment. This technology is called an air source heat pump. The use of a heat pump requires the consumption of electrical energy or heat energy. For example, when a home air conditioner is used for heating in winter, it is a typical air source heat pump. However, the air conditioner will not heat without electricity or heat. Therefore, an air source heat pump is not driven by air energy, but by electrical energy or heat energy. Air source heat pumps can be applied in heating, heating, drying, and other fields.

[0003] After the installation of the air energy pipeline system is completed, the pressure inside the pipeline will decrease after a long period of use. The main reasons for the decrease are as follows: first, micro-leakage may occur at the connection of the pipeline, the flow of hot water in the pipeline decreases, and thus the system pressure decreases; second, in most air energy pipeline systems in China, plastic pipes are used. Under the condition of long-term high temperature and high pressure, the pipeline will expand and deform. When the pipeline expands to a certain extent, the internal volume of the pipeline increases. When the air source heat pump stops working or the temperature of the hot water in the pipeline decreases after thermal cycling, the hot water in the pipeline contracts and the pressure in the pipeline decreases below the threshold value. At this time, the normal operation of the air energy pipeline system will be affected. At this time, it is necessary to supplement the water in the pipeline. In the prior art, when the pressure inside the pipeline decreases to a threshold value, maintenance and after-sales service personnel need to provide on-site service. Generally, they need to visit once or twice a year. The operation is relatively troublesome, time-consuming and labor-intensive, which has a negative impact on the promotion and application of the air source heat pump to some extent and needs to be improved.

[0040] In the embodiment, the frequency conversion control panel 4 needs to be externally connected to a power source through the power input port 41, or directly connected to a central processor of the air energy pipeline system.

[0041] By arranging the pressure sensor 5 on the side of the water pump body 1 close to the water outlet 2, the pipeline pressure inside the water pump body 1 (i.e. the pipeline pressure in the air energy pipeline system) can be detected in real time. When the pipeline pressure drops, the pressure sensor 5 sends a signal to the frequency conversion control panel 4, which controls the operation of the liquid supplement pump 7, so that the liquid in the liquid supplement kettle is continuously input into the water pump body 1, so as to balance the pressure in the air energy pipeline system and ensure the stability of the internal pressure.

[0042] Then, please refer to Figure 5 It can be seen that in the embodiment, the inside of the outer shell 8 is further provided with a touch pcb 9, and the outer surface of the outer shell 8 is fixedly provided with a touch panel 10, and the touch panel 10 and the touch pcb 9 are positionally corresponding.
