Abstract
The utility model provides an air conditioner and a variable throttling device thereof, which can solve the problem of lower energy efficiency of a frequency-variable air conditioner due to incapability of adapting to a rated intermediate refrigerating condition of the air conditioner in the prior art. The technical scheme for solving the technical problem includes that the variable throttling device of the air conditioner comprises an unloading valve and two throttling devices, wherein the unloading valve is connected with one throttling device in parallel and then is serially connected with the other throttling device, and the throttling devices are throttling valves of capillary tubes. By the aid of the variable throttling device, an SEER (seasonal energy efficiency ratio) value can be increased integrally, accordingly, energy efficiency grade of the air conditioner can be increased, cost is greatly lowered, and the air conditioner and the variable throttling device have outstanding advantages.
Description
Technical field
The utility model belongs to household electrical appliance, specifically, relates to the variable restrictor device of air-conditioner.
Background technology
At present, when the domestic variable frequency air-conditioner adopted immutable throttling arrangement, Energy Efficiency Ratio was on the low side, and largely reason is single choke valve throttling.Under the specified cooling condition, can design the optimum value that choke valve guarantees declared working condition; And after reaching the setting room temperature, refrigeration duty diminishes, and air-conditioning can run on the medium and low frequency section for a long time; At this moment air-conditioning is in specified middle cooling condition, and condensing pressure is less, and therefore former single choke valve no longer adapts to; Cause system's height pressure reduction improper, Energy Efficiency Ratio is on the low side, and final SEER is on the low side.
How solving the lower problem of Energy Efficiency Ratio that the specified middle cooling condition of above-mentioned throttling arrangement incompatibility transducer air conditioning causes air-conditioner, then is the problem that the utility model faced.
Summary of the invention
The utility model provides a kind of air-conditioner variable restrictor device and air-conditioner, it can solve incompatibility transducer air conditioning that prior art exists specified in the middle of cooling condition cause the lower problem of Energy Efficiency Ratio of air-conditioner.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is,
A kind of air-conditioner variable restrictor device comprises a unloader and two throttling arrangements, connects with another throttling arrangement after said unloader and one of them throttling arrangement parallel connection again.
Further, said throttling arrangement is choke valve or capillary.
Described two choke valves are throttle valve A and choke valve B, and said unloader is parallelly connected with said throttle valve A, connect with said choke valve B then.
When air-conditioner is in specified cooling condition, the operation of compressor high frequency, discharge capacity is bigger, and pressure is higher, and unloader is opened, and refrigerant flows from left to right, passes through from unloader, then through choke valve B.Throttling so for once, flow is big, satisfies the cooling condition of refrigeration duty when big.
When the refrigeration of specified centre, the operation of compressor medium and low frequency, discharge capacity is less, and pressure is lower, and unloader is obstructed, and refrigerant passes through from throttle valve A, then through choke valve B.Such twice throttling, flow is less, satisfies refrigeration duty cooling condition hour.
Certainly, choke valve can replace with capillary, and unloader remains unchanged; Be that unloader is parallelly connected with capillary A, connect with capillary B then.Principle is consistent, through changing amount of restriction, improves the Energy Efficiency Ratio that the specified middle cooling condition of transducer air conditioning causes air-conditioner, finally improves air-conditioner SEER.The advantage of replacement is also identical, can reduce cost, and improves SEER.Equally, the pressure parameter of length parameter capillaceous, unloader also need be set through the debug results to concrete type.
A kind of air-conditioner comprises the variable restrictor device, and said variable restrictor device comprises a unloader and two throttling arrangements, connects with another throttling arrangement after said unloader and one of them throttling arrangement parallel connection again.
Further, said throttling arrangement is choke valve or capillary.
Further, described two choke valves are throttle valve A and choke valve B, and said unloader is parallelly connected with said throttle valve A, connect with said choke valve B then.
The opening pressure parameter that above-mentioned unloader is concrete can specifically be set according to the operating condition debug results of concrete air-conditioner.
Therefore, the variable restrictor device of the utility model can wholely improve the SEER value, thereby has improved air-conditioner efficiency grade.And, to compare with variable restrictor device electric expansion valve, this installation cost reduces greatly, and greater advantage is arranged.

Wherein: 1, unloader; 2, throttle valve A; 3, choke valve B.
On behalf of refrigerant, arrow flow among the figure.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
A kind of air-conditioner variable restrictor device comprises a unloader and two choke valves, connects with another choke valve after said unloader and one of them choke valve parallel connection again.
Above-mentioned throttling arrangement can solve the lower problem of Energy Efficiency Ratio that the specified middle cooling condition of existing immutable throttling arrangement incompatibility transducer air conditioning causes air-conditioner.Concrete, as shown in Figure 1, a kind of variable restrictor device of air-conditioner comprises unloader 1, throttle valve A 2 and choke valve B 3, unloader 1 is parallelly connected with throttle valve A 2, connects with choke valve B 3 then.
Like Fig. 1, refrigerant flows from left to right, and under the specified cooling condition, pressure is relatively large, unloader 1 conducting, and refrigerant passes through choke valve B 3 throttlings then through unloader 1, throttling so for once, flow is big, guarantees to obtain under the specified cooling condition optimum Energy Efficiency Ratio.
When air-conditioner be in specified in the middle of under the cooling condition, pressure is less relatively, unloader 1 is obstructed, refrigerant is through throttle valve A 2 throttlings, then through choke valve B 2 throttlings, twice throttling, flow is less, guarantees specified in the middle of the cooling condition optimum Energy Efficiency Ratio of acquisition down.
The opening pressure that above-mentioned unloader is concrete can specifically be set according to the operating condition of concrete air-conditioner.Choke valve specifically can be selected according to the operating condition of air-conditioner, can buy on the market.Choke valve can replace with capillary, and operation principle is consistent, repeats no more.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
