Problems solved by technology

[0006] The ECM motor motor has a single function and cannot be applied to different workplaces, such as an ECM motor driven by a thermostat THERMOSTAT, such as figure 1 As shown, since the output ports (W1, W2, Y1, Y2, G) of the thermostat THERMOSTAT output 24VAC signals, the five gear lines T1, T2, T3, T4, and T5 of the ECM motor input 24VAC signals. However, the original HVAC system using PSC fan motors outputs 115VAC or 230VAC, which are not compatible. Therefore, it is necessary to propose a solution to broaden the scope of use of ECM motors in existing HVAC systems, avoid repeated development, and reduce R & D costs and shorten the R & D cycle, the purpose of convenient management

Abstract

An HVAC system and an intermediate connection apparatus applied in the system. In the HVAC system, a PSC motor is replaced by an ECM. The HVAC system comprises an HVAC system controller. The HVAC system controller is provided with a plurality of 115V or 230V alternating-current output ports (W1, W2, Y1, Y2) connected to the motor, and one common port. The ECM is provided with a plurality of 24V low-voltage alternating-current gear input lines, operating parameters of the motor are selected according to the selected gear input lines in a closed state. The HVAC system also comprises an intermediate connection apparatus. The intermediate connection apparatus is connected between the HVAC system controller and the ECM. The intermediate connection apparatus converts 115V or 230V alternating-current electric signals of the plurality of output ports of the HVAC system controller into 24V low-voltage alternating-current signals capable of being identified by the plurality of gear input lines of the ECM. In this way, redevelopment is avoided, research and development costs are reduced, the number of product models is reduced and management is facilitated.

Description

Technical field: [0001] The invention relates to an HVAC system and an intermediate connection device for its application. Background technique: [0002] In recent years, with the increasingly fierce competition in the field of electrical appliances, the technical requirements for products have been continuously improved, such as energy saving and environmental protection, high controllability, intelligent controllability, short development cycle, and low noise. As the core component—the motor, it will undoubtedly become the key component to solve the above technical problems. The motors in traditional household central air conditioners generally use single-phase AC motors PSC, single-phase AC motors, low efficiency, relatively energy consumption, and large noise. Controlling intelligence is low. [0003] With the development of motor technology, permanent magnet synchronous motors have appeared. This type of motor has a motor controller, which uses the motor controller to ...
