Modular heating system of heat pump and variable frequency water pump control method

Abstract

The invention relates to the technical field of heating, in particular to a modular heating system of a heat pump and a variable frequency water pump control method. The modular heating system of theheat pump comprises at least one unit, a first pipeline, a second pipeline, and a plurality of heating devices which are connected between the first pipeline and the second pipeline; and a variable frequency water pump and a third pipeline for feeding cold water are also arranged on the first pipeline. The units are modularized, so that when the modular heating system of the heat pump is used, anappropriate number of units can be activated according to the specific usable area. The modular heating system of the heat pump is convenient and fast to adjust, can be flexibly adapted to different scenes, has strong universality and meets different user demands. On the other hand, when the modular heating system of the heat pump is used, the operation frequency of the variable frequency water pump can be adjusted according to the average inlet water temperature of the units and the average outlet water temperature of the operating unit, and thus, the energy-saving control of the unit outputon the load demand of standard users is realized, the effect of saving electricity is achieved, and the wasting of resources is avoided.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a heat pump modular heating system and a frequency conversion water pump control method. Background technique [0002] Heating, that is, through the design of buildings and cold-proof heating devices, the appropriate temperature can be obtained in the building. The northern coal-to-electricity clean energy heating project not only solves household coal-fired heating, but also drives the demand for heat pump heating in villas and small commercial places. Villa-type household-type heating water machines serve large-scale households, high-end villas and small commercial places, and are not affected by the coal-to-electricity policy. In the future, not only will the traditional coal-to-electricity market in the north continue to explode, but Northwest China, Inner Mongolia and Northeast China will The demand potential of the three provinces will continue to be released. At present,...

AI Technical Summary

Problems solved by technology

At present, due to the different sizes of large houses, villas, high-end residences, and small commercial places, their respective heating requirements are also different. If they all use the same power for heating, there may be insufficient heating demand for large-area places, and for small-area places. There will be excess demand, which will affect the user experience and cause a waste of resources
