Problems solved by technology

The system enters the air, the fault is more difficult to eliminate
[0009] Unknown failures that cannot be prevented and difficult to repair as soon as possible occur in refrigeration equipment, which will affect the life and business of air conditioners; in cold storage and other facilities, chemical goods will occur and cause major economic losses
[0010] Using the visual observation of the observation window, it is more difficult to obtain the quantity data. This observation window is at the front end of the compressor as the starting point of pressure. The loss of refrigerant is exhausted, and the leakage of refrigerant refrigerant cannot be observed at all.

Embodiment Construction

[0023] figure 1 Among them, the connecting pipe (11) between the liquid storage tank and the condenser and the connecting pipe (12) between the liquid storage tank and the throttle valve adopt a non-load-bearing connection, and the connecting pipe can be a common connecting hose or The influence of pipeline connection on the weight measurement of the liquid storage tank is reduced by the spiral shape or the twisted shape. Since the unit weight increases greatly after the refrigerating medium is liquefied, a little involvement does not hinder the judgment of faults and other situations.

[0024] figure 1 Middle (6) can be made of a pressure sensor and a corresponding spring or a flexible base to become a base with an emphasis function; they can be a tension lifting detection device made of a tension sensor component; they can also be a device made of a tension switch or a pressure switch Direct alarm or direct control.

[0025] When the refrigeration system is shut down, the...

Abstract

The invention discloses a device and a method of monitoring the state of a working medium in compression refrigeration system operation. Non-bearing connection is adopted between a liquid storage tankand pipelines of other parts of the refrigeration system, and the state of the refrigeration working medium is monitored by measuring the weight of the liquid storage tank in operation of the system.Whether the operation state of the refrigeration system is normal or not is judged manually or through a computer or whether an alarm or automatic control is implemented through gravity, tension andpressure switches by comparing parameters of weight changes of the liquid storage tank before and after the compressor is started and comparing changes of numerical values of a high-pressure pressuregauge and a low-pressure pressure gauge.

Description

[0001] Technical field [0002] The present invention relates to a compression refrigeration system, and in particular provides a device and an application method for monitoring the state of working fluid in operation for this system. Background technique [0003] In equipment using compression refrigeration systems, such as air conditioners, cold storage, etc., usually in order to monitor the state of the working medium during operation, a pressure gauge is installed at the part where the pressure of the working medium changes greatly. Such as high pressure pressure gauge, low pressure pressure gauge and so on. In special occasions, such as the air conditioner used in automobiles, the refrigerant window is used to observe the flow of refrigerant carrying air bubbles to know the operating state of the working medium. The above-mentioned detection methods are difficult to express the more accurate state of the refrigerant. [0004] For example, in equipment such as air condit...
