Problems solved by technology

Although the cost is relatively low, but the function is single and the storage space is limited. For a complex heat pump system, debugging the system requires multiple program changes and programming of the microcontroller.
[0004] The system method currently adopted is: first, the system engineer debugs the system parameters according to the project plan, and the debugged program is released after the software engineer completes the program change, and continues to debug, forming a cycle. Doing this: First, increase The workload of software engineers and system engineers; the second is to increase the system debugging time

Abstract

The invention provides a heat-pump water heater control and debugging system and a debugging method thereof. An EEPROM memory is added in a control panel of an original heat-pump water heater. Values of heat pump parameters which need to be adjusted by the system (such as an electronic expansion valve opening degree, a time difference, a system temperature point, a current, a temperature safety value and the like) are stored in the memory. When the heat pump parameters need to be adjusted, a computer is connected to the memory, the parameter values are modified on the computer and the modified parameter values are burnt and written to the memory so that the parameters can be changed and adjusted. A process of changing and adjusting the parameters can be completed by a system engineer independently, high flexibility is possessed and system debugging time is greatly shortened. When an internal device in the heat-pump water heater is replaced or the heat-pump water heater is maintained, the heat-pump water heater can reach an optimum work effect only through modifying the parameter values stored in the memory.

Description

technical field [0001] The invention belongs to the technical field of controllers, in particular to a control and debugging system and a debugging method for a heat pump water heater. Background technique [0002] The performance of the heat pump water heater is closely related to the performance of the heat pump control system, and the performance of the control system is the key to ensure the safe, efficient and reliable operation of the heat pump unit system. Therefore, the heat pump control system is the "soul" of the heat pump water heater. With the continuous in-depth research of heat pump technology, the performance of heat pump is also continuously improved. At the same time, the process of realizing is more complicated, and the control algorithm with relatively large operation increases the time in the system debugging process, which affects the debugging efficiency. [0003] There are two main types of controllers currently used in heat pump systems. Large-scal...
