Problems solved by technology

[0002] As an electrical product in people's daily life, air conditioners are very important. When the air conditioner is used for a period of time, it needs to be replaced with a new refrigerant (freon) to make the air conditioner rejuvenate and directly discharge the outside world. On the one hand, it wastes resources and on the other hand causes environmental pollution. Therefore, a special recovery device is required to recover and store
At present, when air conditioners on the market collect fluorine, they judge whether the fluorine collection is clean according to the pipe temperature of the stop valve or the temperature of the air outlet of the external fan artificially.

Embodiment 1

[0045] The invention discloses a fluorine collection control method for an air conditioner, which comprises the following steps:

[0046] Let A1 be the cylinder body temperature of the first air conditioner compressor, B1 be the cylinder body temperature of the second air conditioner compressor, and B1>A1; in this specific embodiment, the A1 is 102~105°C; the B1 It is 170~173°C.

[0047] S1. The air conditioner enters the fluorine collection mode, and the compressor of the air conditioner operates at the highest frequency. The air conditioner detects the compressor cylinder temperature T1 in real time;

[0048] S2. Detect whether the compressor cylinder body temperature T1 satisfies the following conditions:

[0049] When the compressor cylinder temperature T1

[0050]When B1≥compressor cylinder temperature T1≥A1, the air conditioner compressor will run at reduced frequency;

[0051] When the temperature of ...

Embodiment 2

[0053] The invention discloses a fluorine collection control method for an air conditioner, which comprises the following steps:

[0054] Let A2 be the operating power of the first air conditioner, B2 be the operating power of the second air conditioner, and B2>A2; said A2 is 250~500W; said B2 is 700~1200W.

[0055] S1. The air conditioner enters the fluorine collection mode, and the compressor of the air conditioner operates at the highest frequency.

[0056] S2. Detect whether the operating power T2 of the air conditioner satisfies the following conditions:

[0057] When the air conditioner operating power T2

[0058] When B2≥air conditioner operating power T2≥A2, the air conditioner compressor will run at reduced frequency;

[0059] When the operating power of the air conditioner is T2>B2, the fluorine collection is completed, and the air conditioner stops running and gives an alarm.

Embodiment 3

[0061] The invention discloses a fluorine collection control method for an air conditioner, which comprises the following steps:

[0062] Let A3 be the outlet air temperature of the first air conditioner, B3 be the outlet air temperature of the second air conditioner, and B3<A3; A3 is 25-30°C; B3 is 15-20°C.

[0063] S1. The air conditioner enters the fluorine collection mode, and the compressor of the air conditioner operates at the highest frequency.

[0064] S2. Detect whether the outlet air temperature T3 of the air conditioner meets the following conditions:

[0065] When the outlet air temperature of the air conditioner's external unit is T3>A3, the air conditioner compressor runs at the highest frequency;

[0066] When B3≤outlet air temperature of the air conditioner external unit T3≤A3, the air conditioner compressor will run at reduced frequency;

[0067] When the outlet air temperature of the air conditioner's external unit is T3

Abstract

The invention discloses a freon collection control method and a control device of an air conditioner. A detected operation parameter is respectively compared with a preset first standard parameter anda preset second standard parameter, if the operation parameter is between the first standard parameter and the second standard parameter, the compressor operation frequency of the air conditioner isreduced; so that the air conditioner can accurately judge the cleanness of freon collection, and the freon of the air conditioner can be cleaned up.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling fluorine collection of an air conditioner and a control device thereof. Background technique [0002] As an electrical product in people's daily life, air conditioners are very important. When the air conditioner is used for a period of time, it needs to be replaced with a new refrigerant (ie freon) to make the air conditioner rejuvenate and directly discharge the outside world. On the one hand, it wastes resources and on the other hand causes environmental pollution. Therefore need special recovery device to recover and store. At present, when air conditioners on the market collect fluorine, they judge whether the fluorine collection is clean according to the pipe temperature of the stop valve or the temperature of the air outlet of the external fan artificially.
