Abstract
The utility model discloses a coolant recovering and filling device. The coolant recovering and filling device comprises a coolant tank and a combined pressure gage connected with an output pipe of the coolant tank, wherein a high-pressure gage and a low-pressure gage are arranged in the combined pressure gage. The coolant recovering and filling device is characterized in that a temperature display screen is correspondingly arranged right under each of the high-pressure and low-pressure gages, and the two temperature display screens are electrically connected with the corresponding high-pressure and low-pressure gages through controllers. The coolant recovering and filling device has the advantages that the direct monitoring on pressure and temperature in a process of recovering and filling a coolant is realized, and the condition that the precise numerical control on each coolant filling can be reached is ensured.
Description
Technical field
The utility model relates to manufacturing, maintenance and the maintenance of equipment of a kind of refrigeration and air-conditioning equipment, is specially a kind of refrigerant recovering filing provision.
Background technology
At present, in the refrigerant recovering filling apparatus refrigerant charging is generally adopted the nature annotation method, namely by the pressure in the refrigerant tank with coolant charging in refrigeration system, in existing coolant charging process, in order to make the coolant charging amount reach correct control, demonstration numerical value on the table is detecting as judgement by device in big city, known ground is generally for refrigerant charging, to fill refrigerant because needing cryogenic effect, allow refrigeration plant reach the function of temperature control that produces low temperature via circulation line, but the detection table in the refrigerant recovering filling apparatus is single pressure data at present, temperature then needs to table look-up to draw according to the relation of pressure and temperature to obtain, in actual applications, being the site operation personnel more obtains the refrigerant temperature data according to self experience, and this has also caused the monitoring to the coolant charging amount to produce larger error.
The utility model content
The purpose of this utility model is the problem of mentioning in the above-mentioned background technology in order to solve, and a kind of refrigerant recovering filling apparatus that shows simultaneously pressure and temperature is provided.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of refrigerant recovering filling apparatus, comprise refrigerant tank, the multiplemanometer that is connected with described refrigerant tank efferent duct, be provided with high pressure gauge, low-pressure meter in the described multiplemanometer, under the described high and low pressure table all correspondence be provided with a temperature display, described two temperature displays are by controller and corresponding high and low pressure table electric connection.
Preferably, described temperature display adopts LCDs.
Preferably, a single-chip microcomputer is set in the described controller.
Further, described multiplemanometer also includes high and low pressure for defeated pipe, and described multiplemanometer both sides are corresponding being provided with for high pressure valve, the low pressure valve of the described high and low pressure of conduction and cut-off for defeated pipe respectively.
Beneficial effect: the utility model is provided with a temperature display by equal correspondence under the high and low pressure table, two temperature display is electrically connected with the high and low pressure table by controller is corresponding respectively, thereby realized the pressure in the refrigerant recovering filling process, temperature are carried out directly monitoring, guaranteed that each refrigerant filling all can reach accurate Numerical Control.
