Problems solved by technology

[0003] In the existing air conditioners, the adaptability of the nozzle to the flow rate as a quantitative restrictor cannot meet the flow requirements of the variable frequency air conditioner, and can only be used for fixed frequency air conditioners with little change in flow rate; only electronic expansion valves or only parallel settings are used The capillary and solenoid valve or only the solenoid valve and the second nozzle set in parallel can be used as a variable restrictor through opening adjustment or on-off adjustment to meet the flow change requirements caused by the frequency change of the inverter air conditioner, but the seasonal energy efficiency brought Less ideal than SEER

Embodiment 1

[0026] Such as figure 1 As shown, it is an air conditioner equipped with a flow conversion device, including a compressor 1 with pipeline circulation, a four-way valve 2, a condenser 3, and an evaporator 4. The pipeline is equipped with a refrigeration variable flow element, which can adjust the distribution of the total refrigerant flow. In this embodiment, the electronic expansion valve 5 is preferred. A line 7 of a nozzle 6 . The first nozzle 6 is composed of a copper tube and a riser set in the copper tube. A small hole is arranged in the center of the riser along the axial direction. The two ends of the small hole are trumpet-shaped diameter-expanding structures. 4 The inlet end of the cooling direction, the distance between the first nozzle 6 and the inlet end of the evaporator 4 in the cooling direction is 1cm, the first nozzle 6 is composed of a copper tube and a riser installed in the copper tube, and the center of the riser is provided with a small hole in the axial...

Embodiment 2

[0030] The rest is the same as that of Embodiment 1, except that the effective throttling length of the small hole in the riser of the first nozzle 6 is 10 mm.

Embodiment 3

[0032] The rest is the same as that of Embodiment 1, except that the effective throttling length of the small hole in the riser of the first nozzle 6 is 7 mm.

Abstract

The invention discloses an inverter air conditioner, which is characterized in that a cooling variable flow element is provided on the delivery pipe connecting the condenser and the evaporator of the air conditioner, and the cooling variable flow element is used for changing the flow of refrigerant, and the cooling variable flow element and The delivery pipeline between the evaporators is set as at least one pipeline with a first nozzle installed near the inlet end of the evaporator in the cooling direction. The first nozzle is set at the inlet end of the evaporator. The nozzle has the characteristics of instant decompression, which can reduce the heat exchange between the refrigerant and the outside during the input, so that it has a better cooling effect than traditional throttling under the same conditions. Since the refrigerant in the input pipeline is changed from a gaseous state to a liquid state input, the gaseous state of the same mass occupies more space than the liquid state, so the liquid state input increases the condensation space, thereby reducing the outlet pressure of the compressor, thereby reducing the power consumption of the compressor . The invention greatly improves the seasonal energy efficiency ratio of the air conditioner and achieves unexpected effects.

Description

technical field [0001] The invention belongs to the field of frequency conversion air conditioners. Background technique [0002] In the prior art, the SEER value of the air conditioner needs to be improved. In order to improve the efficiency and increase the SEER value of the air conditioner without increasing the cost, an air conditioner capable of increasing the SEER value of the air conditioner is urgently needed. [0003] In the existing air conditioners, the adaptability of the nozzle to the flow rate as a quantitative restrictor cannot meet the flow requirements of the variable frequency air conditioner, and can only be used for fixed frequency air conditioners with little change in flow rate; only electronic expansion valves or only parallel settings are used The capillary and solenoid valve or only the solenoid valve and the second nozzle set in parallel can be used as a variable restrictor through opening adjustment or on-off adjustment to meet the flow change requ...
