Description

A control method for air-conditioning clothing and air-conditioning clothing

Technical Field

The present invention relates to the technical field of air conditioning, and in particular to a control method of air-conditioning clothing and the air-conditioning clothing.

Background technique

As a common cooling device, air conditioners bring great comfort to people's lives. However, since air conditioners can only be installed in fixed places and cannot be carried around, there are certain limitations in the use of air conditioners. For example, in the hot summer, air conditioners cannot be used by people working in the field, traffic police on duty, cleaners who maintain a clean environment, and workers in boiler workshops or foundry workshops.

In order to overcome the limitations of existing air conditioners in use, air-conditioning clothing came into being, which can reduce the perceived temperature of the human body and enable users to work comfortably in extremely hot areas. However, the existing air-conditioning clothing has the problem of high energy consumption and large power consumption during actual use.

Summary of the invention

The embodiments of the present invention provide a control method for air-conditioned clothing and air-conditioned clothing. In order to have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a general review, nor is it intended to identify key/important components or describe the scope of protection of these embodiments. Its only purpose is to present some concepts in a simple form as a preface to the detailed description that follows.

According to a first aspect of an embodiment of the present invention, a control method for air-conditioning clothing is provided, the method comprising: obtaining the external ambient temperature; determining a voltage threshold for the operation of an air-conditioning module according to the external ambient temperature; obtaining the power generation voltage of the air-conditioning clothing; and when the power generation voltage exceeds the voltage threshold, reducing the operating frequency of the compressor.

When the power generation voltage of the air-conditioning clothes exceeds the voltage threshold of the air-conditioning module, that is, the power generation voltage of the air-conditioning clothes is not within the voltage threshold range of the air-conditioning module, the power generation voltage of the air-conditioning clothes is insufficient for the air-conditioning module to operate normally. At this time, the compressor operating frequency is reduced to meet the compressor bus voltage requirement and reduce energy consumption.

Optionally, when the generated voltage exceeds a voltage threshold, reducing the compressor operating frequency comprises: determining a reduction amount of the compressor operating frequency according to an external ambient temperature.

Optionally, the voltage threshold for the operation of the air conditioning module is determined according to the ambient temperature, including: the lowest voltage of the voltage threshold is positively correlated with the ambient temperature. When the ambient temperature is low, the air conditioning module can maintain the air conditioning clothing at a set temperature by operating at a relatively low voltage, thereby reducing energy consumption.

Optionally, obtaining the power generation voltage of the air-conditioning clothing includes: updating the power generation voltage of the air-conditioning clothing according to a set period, retaining only the most recently detected power generation voltage of the air-conditioning clothing, and using the power generation voltage as a basis for whether to execute power supply of the air-conditioning clothing.

Optionally, the power generation voltage of the air-conditioning clothing is updated according to a set period, including: the set period for updating the power generation voltage of the air-conditioning clothing is 10 to 30 minutes.

According to a second aspect of an embodiment of the present invention, an air-conditioning clothing is provided, comprising: an ambient temperature sensor for acquiring the external ambient temperature; a first determination module for determining a voltage threshold for the operation of an air-conditioning module according to the external ambient temperature; a first acquisition module for acquiring the power generation voltage of the air-conditioning clothing; and a first execution module for reducing the operating frequency of the compressor when the power generation voltage exceeds the voltage threshold.

When the generated voltage of the air-conditioning clothing exceeds the voltage threshold of the air-conditioning module, that is, the generated voltage of the air-conditioning clothing is not within the voltage threshold range of the air-conditioning module, the generated voltage of the air-conditioning clothing is insufficient to make the air-conditioning module operate normally. At this time, the first execution module executes to reduce the operating frequency of the compressor to meet the compressor bus voltage requirement and reduce energy consumption.

Optionally, the first execution module is specifically used to: when the generated voltage exceeds a voltage threshold, determine the amount of reduction in the compressor operating frequency according to the external ambient temperature.

Optionally, the first determination module is specifically used to: determine the voltage threshold for the operation of the air conditioning module according to the external environment temperature; wherein the lowest voltage of the voltage threshold is positively correlated with the external environment temperature. When the external environment temperature is low, the air conditioning module only needs to operate at a lower voltage to maintain the air-conditioned clothing at a set temperature, thereby reducing energy consumption.

Optionally, the first acquisition module is specifically used to: acquire the power generation voltage of the air-conditioning clothing, and the setting period for updating the power generation voltage of the air-conditioning clothing is 10 to 30 minutes.

The technical solution provided by the embodiment of the present invention may have the following beneficial effects:

The control method and air-conditioning clothing of the present invention reduce the operating frequency of the compressor to meet the bus voltage requirement of the compressor and reduce energy consumption when the power generation voltage of the air-conditioning clothing exceeds the voltage threshold of the air-conditioning module operation.
