Problems solved by technology

[0003] Among them, the heat pump control algorithm relies on the operation of the soft timer. Since the accuracy of the soft timer cannot be compared with that of the hardware timer, the biggest disadvantage of the technology is that the task execution time cannot be executed accurately.
But for the heat pump system, the time delay is mostly just to make the system reliable and improve the service life. The accuracy of the timer is not high and cannot meet the requirements.

Embodiment Construction

[0011] See Figure 1 to Figure 3 Shown: the present invention comprises initialization module 1, function module 2, sub-equipment 3, initialization module 1 is connected with function module 2, at least one sub-equipment 3, and its implementation method is: the control of each independent sub-equipment 3 is controlled by Controlled by the software control module, each functional module 2 adopts a state machine method, and each time it runs to a certain module, if the current state of the module is not completed, then switch to another module until the next switch back to this module, And the current state is completed before entering the next state to continue running.

[0012] The software loop is a single loop queue timer algorithm.

[0013] The working modes of the air source heat pump air conditioning system include: cooling mode, heat pump mode, air conditioning heat pump mode, slippery mode and idle mode.

[0014] The following table shows the control output of various...

Abstract

The invention relates to the technical field of heat pump air conditioners, in particular to an application method of a polling-method-based multitask scheduling and software timer in an air source heat pump water heater. An air source heat pump air conditioning system comprises an initializing module, function modules and sub-equipment. The initializing module is connected with the function modules and more than one sub-equipment. A realization method of the air source heat pump air conditioning system is characterized in that the control of each independent sub-equipment is realized through a software control module; a state machine method is adopted for each functional module 2; when the system operates a certain module at a time, if the current state of the current module is unfinished, the system is switched to a next module till the system is switched back to the current module; and the module continuously operates in a next state only after the current state is finished. The design is simple and scientific, a great quantity of timed driving tasks in a heat pump system can be well finished, the timing efficiency can be improved, and the flexibility and the applicability are very high.

Description

Technical field: [0001] The invention relates to the technical field of heat pump air conditioners, in particular to a method for controlling and implementing an air source heat pump air conditioner system. Background technique: [0002] The air source heat pump air conditioning system is a system with triple functions of air conditioning, heating, and water heater formed by combining heat pump air conditioners and heat pump water heaters by using heat pump technology. The system has the advantages of high efficiency, energy saving and environmental protection, zero pollution and zero discharge. [0003] Among them, the heat pump control algorithm relies on the operation of the soft timer. Since the accuracy of the soft timer cannot be compared with that of the hardware timer, the biggest disadvantage of the technology is that the task execution time cannot be executed accurately. But for the heat pump system, the time delay is mostly just to make the system reliable and im...
