Embodiment Construction

[0031] Refer below figure 2 Illustrate the setting of one drag multi-type air-conditioning system of the present invention, refer to image 3 The composition of the one-drag multi-type air-conditioning system of the present invention, which is convenient for power management, is described.

[0032] The one-drag multi-type air-conditioning system is an air-conditioning device in which several indoor units (100) are connected to one outdoor unit (200) to fully meet the cooling / heating capacity of a corresponding building. The outdoor unit (200) connected to several indoor units (100) calculates the opening amount of the expansion valve of the indoor unit according to the control command, controls the rotation number of the compressor of the outdoor unit (200), and circulates an appropriate amount of refrigerant.

[0033] In addition, the speed of the condenser fan of the outdoor unit (200) can be controlled according to the operating status of the outdoor unit (200). In order ...

Abstract

An air conditioner system with multiple indoor units is composed of multiple indoor units, one outdoor unit shared by multiple indoor units, a kilowatt-hour meter for measuring the total electric consumption, and a display for displaying the electric consumption of each indoor and the total electric consumption of whole system. Its operation method is also disclosed.

Description

technical field [0001] The invention relates to a one-to-multi-type air-conditioning system that distributes refrigerant to outdoor units connected to multiple indoor units to adjust the indoor air temperature, and especially relates to calculating the power consumption of each room during cooling / heating through the communication between the power display and the outdoor units A one-drag multi-type air-conditioning system for convenient power management and an operation method thereof. Background technique [0002] Recently, with the widespread use of air conditioners, air conditioners are installed in every room of a home or every office of a building. [0003] Such air conditioners are roughly divided into single-type air conditioners suitable for small-scale indoor air conditioning and one-to-multi-type air-conditioning systems installed in large buildings and managed jointly. The general air conditioner is provided with an indoor unit (10) indoors, and an outdoor unit ...
