Abstract
The utility model relates to an improved outdoor machine for cooling and heating type separate air conditioners. The utility model is characterized in that a one-way valve, an auxiliary heating capillary tube, an upper and a lower fork type filters, a bypass electromagnetic valve, a cooling capillary tube and an air and liquid separator are additionally arranged in the existing outdoor machine. After improved, the utility model has the advantages that the backflow of refrigerant is prevented, and the liquid hammer of a compressor is avoided. The heating effect can be improved during heating. The pressure of a bypass part is reduced by refrigerant, so the stop of the machine caused by overpressure can not happen. The air discharging temperature of the compressor and the temperature rise of a motor winding can be reduced by refrigerant, which can guarantee the continuous and normal operation of the compressor. The utility model is suitable for being used as the outdoor machine of various separate air conditioners.
Description
The utility model relates to air-conditioning equipment, particularly a kind of improved cold-warm type separate type air conditioner off-premises station.
The structure of existing cold-warm type separate type air conditioner off-premises station mainly is made up of shell (1), aerofoil fan (2), condenser (3), four-way reversing solenoid valve (4), low-pressure shutoff valve (5), high-pressure stop valve (6), silencer (7), cooling and warming capillary (8), filter (9), compressor (10) and knockout (11) generally as shown in Figure 1.There is following problem in the off-premises station of said structure always: when kind of refrigeration cycle (direction shown in solid arrow among the figure); sometimes because of delivery temperature with motor winding temperature rise is too high shuts down; cisco unity malfunction, but also be easy to generate liquid hammer, compressor is damaged.In addition, heating circulation time (dotted arrow direction in as figure), meet season in spring and autumn; because of evaporating temperature height, condensing pressure also raise; will shut down in case surpass the upper limit, this situation happens occasionally, and delivery temperature and the too high fault that also is easy to generate of motor winding temperature rise.
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of refrigeration, heat in the process can both operate as normal improved cold-warm type separate type air conditioner off-premises station.
Task of the present utility model is that this sample loading mode realizes: this off-premises station includes shell (1), aerofoil fan (2), condenser (3), four-way reversing solenoid valve (4), low-pressure shutoff valve (5), high-pressure stop valve (6), silencer (7), cooling and warming capillary (8), filter (9), compressor (10) and knockout (11), it is characterized in that this machine also set up check valve (12), on, following V shape filter (14 and 13), the auxiliary capillary (15) that heats, bypass solenoid valve (16), cooling capillary (17) and gas-liquid separator (18), gas-liquid separator (18) is communicated with the air intake duct of compressor (10) and the b mouth of four-way reversing solenoid valve (4) respectively, the outlet of bypass solenoid valve (16) is communicated with the air intake duct of compressor (10) by cooling capillary (17), on, following V shape filter (14 and 13) is connected in opposite directions, the left fork port of last V shape filter (14) is communicated with the entrance point of bypass solenoid valve (16), right fork port heats capillary (15) and is communicated with auxiliary, the left fork port of following V shape filter (13) is connected with the outlet of check valve (12), right fork port is connected with filter (9) by a pipeline through condenser (3), and the auxiliary other end that heats capillary (15) and check valve (12) is connected with knockout (11).
Fig. 1 is the fundamental diagram of existing cold and hot type separate type air conditioner off-premises station.
Fig. 2 is a fundamental diagram of the present utility model.
Through after the above-mentioned improvement, following advantage is arranged: the first is when refrigeration, check valve (12) is closed, cold-producing medium must pass through high-pressure stop valve (6), cooling and warming capillary (8), filter (9), upper and lower V shape filter (13 and 14), the auxiliary capillary (15) that heats, knockout (11) enters four-way reversing solenoid valve (4) again after condenser (3) evaporation the logical b mouth of c mouth flow to gas-liquid separator (18), gas-liquid separation relief gaseous coolant is got back to compressor (10), thereby guaranteed that compressor (10) avoids liquid hammer infringement.They are two years old; owing to increased bypass solenoid valve (16); its port of export communicates with cooling capillary (18); and the entrance point of bypass solenoid valve (16) links to each other with the left end of last V shape filter (14); therefore when freezing or heat the state change; can prevent the reverse flow of cold-producing medium and when shutting down the adverse current after the cold-producing medium liquefaction, thereby prevented that compressor from producing liquid hammer, makes compressor be subjected to duplicate protection.In addition, when it experienced high pressure, then the by-passing part cold-producing medium was to low pressure, to keep condensing pressure all the time less than higher limit, can not overload and the accident of shutting down, even also can normally heat continuously season in spring and autumn.They are three years old, bypass solenoid valve (16) and cooling capillary (17) have also played the effect that utilizes the liquid refrigerant gunite to come cooling compressor (10), its principle is to allow the part of the liquid refrigerant that condenser (3) liquid goes out enter in the cylinder of compressor (10) after the throttling step-down cooling of cooling capillary (17), to absorb gasification latent heat when utilizing the cold-producing medium gasification and make the cylinder cooling, thereby reduced the temperature rise of delivery temperature and motor winding, guaranteed that compressor (10) runs well continuously.It four is to have set up auxiliary can improve heating effect after heating capillary (16).
The utility model is suitable for various cold-warm type separate type air conditioner off-premises stations to be adopted.
