Abstract
The invention relates to an air conditioner, in particular to a split type air conditioner cooling medium ball valve connecting tubing structure, which solves the problems that an evaporator and a connecting tubing need to be pumped, and is inconvenient for injecting cooling medium before installing a split type air conditioner, the air conditioner has poor refrigerating effect, large power consumption and high noise when not completely pumping out air, the air conditioner is easily to thermally jumped, and the service life of a compressor is shortened when the vacuum degree is excessive and the cooling medium is injected with small quantity. The technical scheme is that a cooling medium connecting tubing with thread pipe orifices is connected between an evaporator pipe inlet in an indoor set and an expansion valve outlet in an indoor set, wherein thread pipe orifices on the two ends of the cooling medium connecting tubing and the front of a thread pipe orifice on the end portion of the evaporator pipe are provided with ball valves. The invention not only leads the evaporator pipe and a cooling medium connecting tubing to be pumped out air when in production, but also to be injected with quantitative cooling medium liquid, and the vacuum degree and the injection amount are standard, and the ball valves are closed after being charged with liquid. When installs the air conditioner, only the expansion valve, an evaporator and the pipe orifice of the connecting tubing are screwed, and then each ball valve is opened.
Description
Technical field
The invention belongs to air regulator, particularly a kind of evaporimeter is found time convenience, the fluid injection standard of finding time, noise are little, the divided air conditioner coolant ball valve connection piping structure of little power consumption, good refrigeration effect.
Background technology
Generally, air-conditioner is to utilize in the circularly cooling or heating chamber of refrigerant.Integral air conditioner is to be formed in the machine by compressor, condenser, expansion valve, evaporimeter, and is contained on wall hole, room or the window; Detachable air conditioner is installed evaporimeter in indoor set, and compressor, condenser, expansion valve are installed in off-premises station, and utilizes coolant piping to connect between off-premises station that separates and the indoor set.
Fig. 1 is according to the detachable air conditioner indoor unit and outdoor unit of prior art and connecting pipings oblique view therebetween.
As shown in Figure 1, detachable air conditioner in the past is made of off-premises station 11 and indoor set 10.Off-premises station is provided with compressor 1, condenser 2, expansion valve 3 and outdoor fan 12 for 11 li.During operation, compressor 1 is compressed into the gaseous coolant of low-temp low-pressure the refrigerant of HTHP, condenser 2 makes the refrigerant air heat release towards periphery of compressor 1 compression and is condensed, expansion valve 3 expand into the low-temp low-pressure refrigerant to the refrigerant of condenser 2 condensations, and outdoor fan 12 is to condenser 2 forced conveyance outdoor airs.Indoor set is provided with evaporimeter 8 for 10 li.Evaporimeter 8 makes the refrigerant of expansion valve 3 expansions absorb the surrounding air heat and evaporates.Evaporimeter 8 in compressor 1 in the off-premises station, condenser 2, expansion valve 3 and the indoor set utilizes coolant connecting piping 4 to be connected.
Need deflate and inject refrigerant whole medium circulation pipeline when existing detachable air conditioner is installed, for this reason, process duct of welding on condenser is responsible for, medium circulation pipeline is vacuumized and inject refrigerant liquid by process duct, then process duct is flattened, welding is shut, but the above-mentioned existing electrolyte filling method of bleeding is very loaded down with trivial details, as more difficult in off-premises station work high above the ground time operation, and such electrolyte filling method difficult quality guarantee of finding time, excessive or the air of exhaust usually takes place do not drain clean phenomenon, excessive in exhaust, refrigerant injects more after a little while, and air-conditioner heat is easily jumped, and makes decline of compressor life-span and refrigeration bad; Not during emptying, the air-conditioner power consumption is many, noise big and refrigeration is not good yet at air.
Summary of the invention
The present invention provides a kind of divided air conditioner coolant ball valve connection piping structure in order to solve the above-mentioned technical problem that exists in the prior art, when it is produced in air-conditioner, coolant connecting piping interface at indoor machine evaporation and off-premises station respectively increases a ball valve, produce and assemble when finishing both with evaporimeter, vacuumize and inject an amount of refrigerant and close ball valve then together with pipe arrangement, operation was both very easy like this, and the reservoir quantity of finding time is also suitable, in giving the user installation air conditioning chamber, during outer machine, need not to vacuumize again and fluid injection, only need with the coolant connecting piping two ends be bolted in open behind off-premises station expansion valve interface tube and the indoor machine evaporation interface tube ball valve.
Technical scheme of the present invention is in the refrigerant circulation circuit that constitutes in off-premises station and indoor set,
Include: be connected the coolant connecting piping with the mouth of pipe that is spirally connected between the expansion valve outlet in inlet of evaporator pipeline in the indoor set and the off-premises station, feature is: the mouth of pipe front that is spirally connected of the be spirally connected mouth of pipe and the evaporator pipeline end at its coolant connecting piping two ends also is equipped with ball valve.
Above-mentioned ball valve is installed in the coolant connecting piping two ends and it is spirally connected between the mouth of pipe.
Above-mentioned ball valve is installed in evaporimeter refrigerant pipeline end and it is spirally connected between the mouth of pipe.
Above-mentioned ball valve is installed in the expansion valve outlet and is spirally connected between the mouth of pipe and the expansion valve.
Advantage and good effect: the present invention mouth of pipe front that is spirally connected at evaporimeter and connecting pipings two ends when producing respectively increases a ball valve.When producing assembling, evaporimeter and connecting pipings vacuumized and inject an amount of refrigerant liquid, when giving the user installation air conditioning chamber, need not to vacuumize again, fluid injection, only need with the coolant connecting piping two ends be bolted in open behind off-premises station expansion valve interface tube and the indoor machine evaporation interface tube ball valve, the difficulty of vacuum pumping liquid injection when having saved existing detachable air conditioner and installing, in addition, because of vacuum pumping liquid injection is satisfied the criteria, solved air-conditioning jump heat,, the problem that the compressor life-span descends, power consumption is many, noise is big and refrigeration is bad.
