Temperature control device and method, electric cabinet and air-conditioner

Abstract

The invention provides a temperature control device and method, an electric cabinet with the control device and an air-conditioner. The temperature control device comprises a control part and a plurality of temperature sensors, the temperature sensors are arranged at the different positions of a temperature control object so as to detect temperature values at the multiple different positions, the control part is connected with the temperature sensors and enables the detected temperature values at the multiple different positions to be compared with a first temperature preset value, and when the temperature values are larger than or equal to the first temperature preset value, the control part conducts control to do cooling operation and / or alarming treatment on the temperature control target. According to the temperature control device, the multiple temperature sensors conducts multi-point sampling, and therefore accurate temperature control can be carried out at the multiple positions at the same time.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a temperature control device and method, an electric control box with the control device, and an air conditioner. Background technique [0002] At present, the electrical components in the electric control box or airborne starter cabinet used by the central air conditioner are dense, the gap between the components is too small, and some components generate a lot of heat. Now most of them adopt the form of opening shutters and installing fans to dissipate heat. The hidden danger of excessive temperature rise in the electric control box will affect the IP level of the box. Contents of the invention [0003] In view of this, the object of the present invention is to provide a temperature control device, a method, an electric control box and an air conditioner with the control device, which can accurately control the temperature of the components in the electric control bo...
