The utility model content
Be cost and the irreconcilable shortcoming of flow that overcomes throttling arrangement, the utility model provides a kind of throttling arrangement and air-conditioner of convertible frequency air-conditioner, make the flow of cold-producing medium to change, cost is low, control program is simple, be convenient to control, solved cost and the irreconcilable problem of flow of throttling arrangement.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of throttling arrangement of convertible frequency air-conditioner, throttling arrangement be included in pipeline according to the operation of air conditioner situation control the gate valve of flow of refrigerant, first throttle element and the second section fluid element of adjusting refrigerant flow rate in pipeline, described first throttle element is connected with gate valve in pipeline, at the two ends of gate valve second section fluid element in parallel, the cost of throttling arrangement is low, is convenient to control.
Convertible frequency air-conditioner comprises throttling arrangement, evaporimeter, condenser, cross valve and compressor, throttling arrangement one end is connected with the evaporimeter that the refrigerant liquid of the throttling arrangement of flowing through is evaporated to steam, the other end is connected with the condenser that will be condensed into from the high-pressure refrigerant vapor of compressor liquid, be connected cross valve and the refrigerant vapour in evaporimeter is sucked and be compressed to certain condensing pressure between evaporimeter and condenser and arrange compressor to condenser, evaporimeter is connected with the first throttle element, and condenser is connected with gate valve.
First throttle element, second section fluid element are choke valve or capillary.
The first throttle element is identical restricting element or different restricting elements from the second section fluid element.
When gate valve is opening, the first throttle element works independently; The gate valve of the cooperative control flow of refrigerant of two restricting elements series connection during for closed condition, the work of the open and close controlling restricting element by gate valve reaches the purpose of controlling refrigerant flow, and cost is low.
Another kind of technical scheme of the present utility model is: a kind of convertible frequency air-conditioner comprises the throttling arrangement of convertible frequency air-conditioner described above.
The beneficial effects of the utility model are, can control the size of refrigerant flow in pipeline, and cost is low, and control program is simple, are convenient to control, and have solved cost and the irreconcilable problem of flow of throttling arrangement.
Description of drawings
Be specifically described below in conjunction with throttling arrangement and the air-conditioner of accompanying drawing to convertible frequency air-conditioner described in the utility model.
Fig. 1 is structural representation of the present utility model.
As shown in Figure 1, gate valve 1, first throttle element 2, second section fluid element 3, evaporimeter 4, condenser 5, cross valve 6, compressor 7.
The specific embodiment
As shown in Figure 1, convertible frequency air-conditioner comprises throttling arrangement, evaporimeter 4, condenser 5, cross valve 6 and compressor 7, and throttling arrangement one end is connected with evaporimeter 4, and the other end is connected with condenser 5, is connected cross valve 6 and compressor 7 between evaporimeter and condenser.In process of refrigerastion, the cold-producing medium that flows into through throttling arrangement flow into evaporimeter 4, refrigerant liquid is evaporated to steam, compressor 7 sucks the refrigerant vapour in evaporimeter, be compressed to certain condensing pressure, then arrange to condenser 5, condenser 5 is cooling and be condensed into liquid with the refrigerant vapour of high pressure, flow in throttling arrangement, carry out periodic duty.
Throttling arrangement is included in pipeline the gate valve 1 of controlling flow of refrigerant, first throttle element 2 and the second section fluid element 3 of adjusting refrigerant flow rate in pipeline.First throttle element 2 is connected with gate valve 1 in pipeline, and at the two ends of gate valve 1 second section fluid element 3 in parallel, evaporimeter 4 is connected with first throttle element 2, and condenser 5 is connected with gate valve 1, and control program is simple, easy operating.
First throttle element 2, second section fluid element 3 are choke valve or capillary, and the first throttle element can be identical with the second section fluid element, also can be different.The cost of capillary and choke valve is low, and it is used in combination, and not only can control the flow of cold-producing medium, and low price, saves cost.
Generally, when air-conditioning was in specified refrigeration work, gate valve 1 was opened, and being flowed through by the cold-producing medium that flows out in evaporimeter 4 in pipeline, first throttle element 2 is rear flows to condenser 5 by gate valve 1.Because gate valve 1 is in parallel with second section fluid element 3, when gate valve 1 is in open mode, the branch road of gate valve is with the branch, short-circuit of second section fluid element, thereby cold-producing medium is without second section fluid element 3, only through first throttle element 2 and gate valve 1, worked independently by first throttle element 2 and carry out throttling, the flow of cold-producing medium is larger, the needs of refrigeration when having satisfied normal operation.When air-conditioning is in cold operation, perhaps when refrigeration or the middle special circumstances that heat, gate valve 1 is closed, stoping cold-producing medium to flow through from the branch road of gate valve, thereby be to flow through to flow to condenser 5 after first throttle element 2 and second section fluid element 3 by the cold-producing medium that flows out in evaporimeter 4 in pipeline, is by the common work that is cascaded of first throttle element 2 and second section fluid element 3, make the flow of cold-producing medium diminish, the performance Energy Efficiency Ratio reaches adjust flux, the purpose of being convenient to control.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
