Problems solved by technology

Generally speaking, when the refrigerant in the air conditioner is reduced to a certain extent, its energy efficiency ratio will be significantly reduced. On the one hand, the cooling and heating capabilities will decrease, which will affect the normal use of users; It will cause the compressor of the air conditioner to burn out, which will seriously affect the service life of the air conditioner, so it is necessary to check whether the refrigerant in the air conditioner is sufficient
The current detection method often has a simple judgment logic, and the following problems often occur: it may not be possible to detect the lack of refrigerant in the air conditioner, which reduces the service life and operational reliability of the air conditioner; false detection and false protection may occur, In fact, there is no lack of refrigerant, but the lack of detection results is given, which affects the normal use of users and reduces the user experience

[0165] Compared with the first embodiment, step S406 and step S407 are mainly added in the embodiment of the present application, which involves the principle that: for the second heat exchanger, when there is a lack of refrigerant, due to the flow through the second The refrigerant flow rate of the heat exchanger is small, and at this time, the refrigerant will exchange heat too much, causing the temperature of the second coil to be close to the external ambient temperature. Therefore, in the embodiment of the present application, it is added to detect whether there may be a lack of refrigerant by comparing the relationship between the temperature of the second coil and the temperature of the external environment for a period of time after the start of the air conditioner. If the temperature of the second coil is greater than the temperature of the external environment by more than 2 degrees Celsius, Then it is likely that there is a lack of refrigerant, otherwise it means tha...

Abstract

The invention discloses an air conditioner detection method, an air conditioner control method and device and air conditioner equipment.The detection method comprises the following steps: detecting an operation mode of the air conditioning equipment, collecting related coil pipe temperature and compressor exhaust temperature corresponding to the operation mode, and detecting whether the air conditioning equipment lacks a refrigerant or not through hierarchical judgment logic. The control method is based on the detection method, and when it is determined that the air conditioner lacks the refrigerant, the air conditioner is controlled to stop. According to the embodiment of the invention, the success rate of correctly detecting that the air conditioning equipment lacks the refrigerant can be improved, so that the operation of the air conditioning equipment is safer and more reliable, air conditioner damage accidents are reduced, and the service life of the air conditioning equipment is effectively prolonged; and detection errors of the refrigerant lacking state can be reduced, the situation that normal use of a user is affected by mistaken protection of the air conditioner equipment is avoided as much as possible, and the working stability of the air conditioner equipment and the comfort degree of the user are improved. The air conditioner detection method can be widely applied to the technical field of air conditioners.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner detection method, control method, device and air conditioner. Background technique [0002] Air conditioner is a commonly used household appliance, which plays a great role in daily life. It can flexibly work in cooling or heating mode according to the actual weather temperature, which brings great convenience to people's work and life. Its working principle is mainly to complete the heat exchange between indoor and outdoor air through the refrigerant absorbing or releasing heat in the gaseous state and liquid state transformation, so that the indoor environment is more comfortable. [0003] Refrigerant is an indispensable part of the air conditioner, and its adequacy has a very important impact on the normal operation of the air conditioner. Generally speaking, when the refrigerant in the air conditioner is reduced to a certain extent, its ...
