Energy-saving air conditioner with one outdoor unit and two indoor units

Abstract

The invention discloses an energy-saving air-conditioner, which comprises the following parts: two indoor sets within two evaporators and outdoor set within compressor and condenser, wherein the outlet of two indoor sets connects liquid accumulator through pipe; the outlet of liquid accumulator connects the inlet of two compressors separately; the inlet and outlet of two compressors connect the condenser through one-way valve; the other end of condenser two outlet connects the evaporator inlet of two indoor sets through paralleling pipe of capillary and electromagnetic valve; the equilibrate capillary is connected among the paralleling pipe of two capillaries and electromagnetic valve.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an energy-saving one-driver-two air conditioner. Background technique [0002] Existing household one-to-two air conditioners can basically be divided into two types: one is composed of two sets of compressors, condensers, one-way valves, capillary tubes, four-position electromagnetic reversing valves, and axial fans installed in one indoor unit. Inside, two sets of complete heating and cooling systems are formed with two indoor units through two sets of independent pipelines. When working, according to the needs of users, the two systems can run at the same time or separately. This type is essentially a simple combination of two sets of one-drag and one-split air conditioners. Its cost is relatively high, and the outdoor unit is bulky. This dual-compressor one-driver-two air conditioner has two condensers in the outdoor unit, and only half of the condensers can be used when the unit is ru...

AI Technical Summary

Problems solved by technology

Although this type of air conditioner has only one outdoor unit, the power consumption of the compressor is large, especially when the unit is running alone, the energy loss is serious and the electrical load is large.

In order to solve this problem, a variable frequency motor is used to automatically adjust the motor speed according to the power demand to save energy consumption, but the problem is that the control circuit is complicated, the cost is high, and consumers are not easy to accept it.
