Abstract
The invention belongs to the field of large water source heat pump unit manufacturing and particularly relates to a process for recovering a residual gas refrigerant in a heat pump system manufacturing process. The process includes the steps of recording the filling speed when a storage tank overflows, moving the storage tank back to a recovery station when the pressure of the storage tank is lower than 0.5 MPa or the filling speed is lower than 30% of that for a full storage tank, connecting a refrigerant recovery machine between the tank and a receiving tank, opening the refrigerant recovery machine, discharging air out of a pipe, connecting the pipe to the receiving tank, continuing to work when the gauge pressure of an air inlet of the refrigerant recovery machine reaches 10 min . The process for recovering the residual gas refrigerant in the heat pump system manufacturing process ensures the refrigerant filling speed in production, can bring considerable economic benefits annually and avoids wastage.
Description
Technical field
The invention belongs to larger water source source pump manufacture field, particularly relate to a kind of in heat pump manufacture process the recovery process to remaining gaseous cold-producing medium.
Background technology
Under the integrated environment that depressed, the economic downstream pressure of manufacturing industry environment is larger, the survival of enterprise, not only by order, more should be noted each details concerned in cost,
A lot of producer have ignored the value of remaining gaseous cold-producing medium in larger cold-producing medium storage tank, confirm according to test, with common refrigerant filling machine, during filling refrigerant, when only remaining gaseous refrigerant in storage tank, filling speed is very slow, be difficult to ensure manufacturing schedule, and " slack tank " of now resigning from office is for 400Kg capacity, reclaim 10 tank R22 " slack tank ", the conclusion of test is that every tank about has and there is no method more than the cold-producing medium of 40Kg and reclaim completely.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of in heat pump manufacture process the recovery process to remaining gaseous cold-producing medium.Solve the thorough recovery problem to cold-producing medium " slack tank " interior residual air, and manufacturing schedule and economic interests will be ensured, and considerable economic benefit can be brought every year.
The present invention realizes like this, recovery process to remaining gaseous cold-producing medium in a kind of heat pump manufacture process, comprise: record filling speed during storage tank flood irrigation, when the force value in storage tank is lower than 0.5MPa, or filling speed is less than 30% during canful, this storage tank is fallen back on recovery station, coolant reclaiming machine is connected between storage tank and recycling can, first open coolant reclaiming machine by after the discharge of channel interior air, be connected to by pipeline and receive on storage tank, coolant reclaiming machine air inlet to reach when gauge pressure is zero continuous firing 10min again.
Further, the quantities received of recycling can is less than or equal to 80% of its rated capacity.
Further, the reclaim line of coolant reclaiming machine and storage tank arranges device for drying and filtering.
Compared with prior art, beneficial effect is in the present invention: this invention ensures that the speed of producing upper filling refrigerant, and can bring considerable economic benefit every year, avoid waste.Simultaneously, reclaimer required for the inventive method is the equipment that general heat pump manufacturing enterprise has, do not need extra buying, other pipeline fittingses, valve member is with low cost, easy and simple to handle, considerable economic benefit can be brought every year, be example after testing, be the CM6000 shape coolant reclaiming machine of certain company, its recovery speed is about 70 ~ 80Kg/h, its rated power is 2.2Kw, for 400KgR22 storage tank, about 0.5h is thoroughly recyclable, yield is 40Kg, be worth 14 yuan/Kg, calculate in recovery with 6h 20 day every day, 20 days recyclable 9600Kg cold-producing mediums, be worth about 13,000 yuan, power consumption is hundreds of unit only, all the other filters dropped into, the expenses such as tube connector are also very cheap and be disposable input.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Recovery process to remaining gaseous cold-producing medium in a kind of heat pump manufacture process, comprise when the force value in storage tank is lower than 0.5MPa, its filling speed is less than 30% during canful, this storage tank is fallen back on recovery station, coolant reclaiming machine is connected between storage tank and recycling can, first open after channel interior air discharges by recycling machine, then be connected to by pipeline and receive on storage tank, recycling machine air inlet to reach when gauge pressure is zero continuous firing 10min again.Ensure that the quantities received of recycling can is less than or equal to 80% of its rated capacity.The reclaim line of coolant reclaiming machine and storage tank arranges device for drying and filtering.The compressor of coolant reclaiming machine inside absorbs in storage tank after residual air, and its boil down to is liquid, is discharged into adapter, discharges air, be connected to reception storage tank, complete the conversion of gaseous state picture liquid state, recovery.
Be example after testing, be the CM6000 shape coolant reclaiming machine of certain company, its recovery speed is about 70 ~ 80Kg/h, and its rated power is 2.2Kw, for 400KgR22 storage tank, about 0.5h is thoroughly recyclable, and yield is 40Kg, is worth 14 yuan/Kg, calculate in recovery with 6h 20 day every day, 20 days recyclable 9600Kg cold-producing mediums, are worth about 13,000 yuan, and power consumption is hundreds of unit only.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
