Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0020] like figure 1 As shown, a conventional refrigeration system mainly includes an indoor side 1 and an outdoor side 2 connected by refrigerant pipelines. The main refrigeration components in the indoor side 1 include an evaporator 6 and a corresponding indoor unit fan 5; The main refrigerating components include a compressor 7, a throttling component 11, a condenser 9 and an outdoor unit fan 10 corresponding thereto.

[0021] When the refrigeration system is running, the compressor 7 starts, and the refrigerant becomes a high-pressure and high-temperature gas in the compressor 7, and enter...

Abstract

The invention provides a refrigerating system. The refrigerating system comprises a thermistor and a relay. The thermistor is arranged on one refrigerating part of the refrigerating system; a signal end of the relay is connected with the thermistor to form a signal loop, and a control end of the relay is connected with a power supply wire of the refrigerating system to form a control loop; the relay comprises a first control position and a second control position; the resistance value of the thermistor is changed according to the temperature change of the refrigerating part; the current valuein the signal loop is in an inverse ratio to the resistance value; when the current value is lower than a first preset value, the relay is positioned in the first control position; and when the current value is higher than a second preset value, the relay is positioned in the second control position. The operation of the refrigerating system can be automatically controlled only through the thermistor and the relay without needing to use a main board, so that the development and manufacturing cost of the refrigerating system is reduced, and the adaptability is high.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular to a refrigeration system. Background technique [0002] At present, many temperature detectors are often used in air-conditioning equipment to detect the temperature of the environment and equipment components, so as to obtain data to improve the control mode of the air-conditioning equipment. For example, in many air-conditioning equipment, temperature detectors such as exhaust temperature sensor, pipe temperature sensor, and environment temperature sensor are used to detect temperature data. [0003] In some air conditioners with simple structures, only the exhaust temperature sensor is kept to ensure the normal operation of the air conditioner. For this reason, it is necessary to add a motherboard to the exhaust temperature sensing package to realize the control of the air conditioner. In this way, the added mainboard cannot play its full role, and the ...
