A kind of optimization device and method based on ptc electric heating system

Abstract

The invention discloses an optimization device and method based on a PTC electric heating system. and the second fixing sleeve are respectively connected to the bracket by bolts, the PTC heating element is installed on the bracket, and the folded ends of several heat conducting elements are fixedly connected to the bracket. The method includes step S1: installing the second fixing sleeve near the heat sink A temperature sensor, and detect the temperature ε of the second fixed sleeve; step S2: select the length of the radiator; step S3: select the length of the ceramic block. The invention arranges the PTC thermistors and the ceramic blocks at intervals, so that the distance between each PTC thermistor and the ceramic blocks is the same, and improves the heat transfer uniformity of the PTC electric heating plate, and eliminates heating by setting oval ceramic parts. It is convenient to choose the length of the ceramic block while improving the internal clearance of the parts. In the test stage, the ceramic block can be reused for testing, saving costs.

Description

technical field [0001] The invention relates to the technical field of air conditioning and heating, in particular to an optimization device and method based on a PTC electric heating system. Background technique [0002] In order to improve heating in winter, existing air conditioners mainly use indoor auxiliary electric heaters to meet user needs, while the current auxiliary heaters mainly include tubular electric heaters. The surface load of the above electric heating methods is limited, and the indoor unit is limited. The power in the space cannot be too large, especially for fixed-speed products, the power of auxiliary electric heating accounts for more than 50% of the power consumption of the whole machine in winter, and the contradiction is becoming more and more prominent. In addition, at low room temperature, the heating effect of the tubular electric heater is slow and the heating effect is not ideal, which is one of the reasons for customer complaints. The PTC hea...
