Problems solved by technology

[0002] At present, the inverter air conditioner uses the nozzle check valve as the cooling check valve device, which can effectively improve the cooling energy efficiency ratio of the inverter air conditioner, but at the same time, the heating energy efficiency ratio is not very ideal.
[0003] In the prior art, the adaptability of the nozzle check valve as a quantitative throttling element to the flow rate cannot meet the flow rate 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 electronic expansion valves are used. Capillary tubes and solenoid valves arranged in parallel or only solenoid valves and second nozzles arranged in parallel as variable flow throttling devices can heat and change flow, but the energy efficiency ratio is not ideal

Embodiment 1

[0037] Such as figure 1 As shown in , 2, an improved inverter air conditioner includes a compressor 1, a four-way valve 2, a condenser 3 and an evaporator 4, and the delivery pipeline connecting the condenser 3 and the evaporator 4 is arranged according to the cooling flow direction. A variable flow throttling device and a refrigeration check valve device, the conduction direction of the refrigeration check valve device points to the condenser 3, the refrigeration check valve device is close to the evaporator 4, and the refrigeration check valve is installed at a distance from the inlet of the evaporator in the cooling direction End 80cm, the cooling check valve device adopts the nozzle check valve 6, the variable flow throttling device adopts the electronic expansion valve 5, and the heating throttling is realized by adjusting the opening of the electronic expansion valve 5, the nozzle check valve 6 includes the valve body 11. The movable spool 13 and the fixed valve seat 12,...

Embodiment 2

[0043] Such as image 3 As shown, the rest is the same as that of Embodiment 1, except that three nozzle check valves 6 arranged in parallel are used as the three-way refrigeration check valve device and the electronic expansion valve 5 is used as the variable flow throttling device. Realize unexpected significant increase in APF value.

[0044] The following is a year-to-year year-to-year experiment on the energy efficiency ratio of an inverter air conditioner using three nozzle check valves 6 as a three-way refrigeration check valve device and one electronic expansion valve 5 as a variable flow throttling device according to national standards. The experimental data is tabulated as follows:

[0045]

[0046] It can be seen from the above experimental data that the APF value of the inverter air conditioner using the prior art is 4.797, while the APF values ​​obtained by using the technical solution of the present invention are 5.841, which is significantly improved.

Embodiment 3

[0048] Such as Figure 4 As shown, the rest is the same as that of Embodiment 1, except that the one-way valve 8 and the capillary tube 9 arranged in parallel are used as a one-way refrigeration check valve device and the electronic expansion valve 5 is used as a variable flow throttling device.

Abstract

The invention discloses an improved frequency conversion air conditioner. One or more refrigeration one-way valve devices with throttling function arranged in parallel are arranged near the evaporator on the delivery pipeline connecting the condenser and the evaporator. The conduction direction of the valve device points to the condenser, and it is characterized in that a variable flow throttling device is provided near the condenser on the delivery pipeline connecting the refrigeration check valve device and the condenser. The device is equipped with a refrigeration check valve device at the end close to the evaporator, which can effectively improve the energy efficiency ratio of the inverter air conditioner, and is equipped with a heating throttling element at the end close to the condenser, which can effectively improve the heating energy efficiency ratio of the inverter air conditioner. The invention can effectively improve the annual energy efficiency ratio of the frequency conversion air conditioner and bring unexpected effects.

Description

technical field [0001] The invention belongs to the field of an improved inverter air conditioner. Background technique [0002] At present, the inverter air conditioner adopts the nozzle check valve as the cooling check valve device, which can effectively improve the cooling energy efficiency ratio of the inverter air conditioner, but at the same time, the heating energy efficiency ratio is not very ideal. [0003] In the prior art, the adaptability of the nozzle check valve as a quantitative throttling element to the flow rate cannot meet the flow rate 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 electronic expansion valves are used. Although the capillary tube and the electromagnetic valve arranged in parallel or only the electromagnetic valve and the second nozzle arranged in parallel can be used as the variable flow throttling de...
