The specific embodiment
Below in conjunction with the drawings and specific embodiments, window air conditioner of the present invention is described in further detail:
Other operation principle and the prior art of window air conditioner of the present invention are identical, can be with reference to prior art, thus no longer narration, and with reference to the Reference numeral of prior art, the present invention and the difference of prior art are that the refrigerant running system of window air conditioner is different, are described in detail below:
As Fig. 3, shown in 4, energy-saving window air conditioner of the present invention, comprise compressor 20, evaporimeter 5 (seeing Fig. 1), condenser 19, indoor fan, outdoor fan, shell, chassis 1 and be arranged on the baffle plate 7 that whole air-conditioning is divided into indoor section and outdoor section on chassis, on the refrigerant pipe connecting between compressor 20 and evaporimeter 5, be connected with the 2nd gas-liquid separator 30, connect on the refrigerant pipe between compressor 20 and evaporimeter 5 and be provided with the 2nd magnetic valve 32, be arranged on the both sides that the refrigerant inflow pipe 35 on the 2nd gas-liquid separator 30 tops and gaseous coolant effuser 37 lay respectively at the 2nd magnetic valve 32, refrigerant inflow pipe 35 is between evaporimeter 5 and the 2nd magnetic valve 32, on refrigerant inflow pipe 35, be provided with the 1st magnetic valve 31, gaseous coolant effuser 37 is between compressor 20 and the 2nd magnetic valve 32, on gaseous coolant effuser 37, be provided with the 3rd magnetic valve 33, between the 3rd magnetic valve 33 and compressor 20, be provided with the refrigerant discharging tube 39 being connected with the 2nd gas-liquid separator 30 bottoms, on refrigerant discharging tube 39, be provided with the 4th magnetic valve 34.
Described the 2nd gas-liquid separator 30 is arranged on indoor section, near baffle plate 7, and the position nearest with compressor 20.Be fixed on chassis 1 at the 2nd gas-liquid separator 30, between the 2nd gas-liquid separator and chassis 1, be provided with damping pad 38.Refrigerant discharging tube 39 is fixed on the outer wall of the 2nd gas-liquid separator 30 by stator 36.
Below operation principle of the present invention is elaborated:
As shown in Figure 5, in normal operation situation, magnetic valve 31,33,34 cuts out, and 32 open, and now window machine running at full capacity, provides maximum refrigerating capacity.
As shown in Figure 6, in the time that room temperature reaches target temperature (as 18 ℃), magnetic valve 32,34 cuts out, and magnetic valve 31,33 is opened simultaneously.At this moment enter second gas-liquid separator 30 by magnetic valve 31 by refrigerant inflow pipe 35 from the low-temp low-pressure refrigerant of evaporimeter gas-liquid mixed state out, the 2nd gas-liquid separator 30 the insides by screen pack by gaseous state and liquid refrigerant separately after, the refrigerant of gaseous state enters compressor 20 air intake ducts through magnetic valve 33 and forms kind of refrigeration cycle, and liquid refrigerants is stored in the 2nd gas-liquid separator 30 the insides, magnetic valve 31 in the time that the coolant quantity of the 2nd gas-liquid separator 30 the insides reaches certain storage, 33, 34 close, magnetic valve 32 is opened, after after a while, the refrigerant of machine kind of refrigeration cycle the inside will reduce like this, now the refrigerating capacity of machine can reduce, be able to maintain the refrigerating capacity of room temperature, meanwhile the input power of compressor also can significantly reduce, reach energy-conservation effect.
As shown in Figure 7, in the time that room needs large refrigerating capacity, magnetic valve 31,33 cuts out, magnetic valve 32,34 is opened, the liquid refrigerants that is stored in like this 2nd gas-liquid separator 36 the insides will enter cooling cycle system by discharging tube 39, machine has recovered again running at full capacity, and maximum refrigerating capacity is provided.
The advantage of structure of the present invention is: after increasing a gas-liquid separator and several control valve, can keep the temperature in room long-term be stabilized in target temperature point, people inside feels can be very comfortable, now machine can automatically not stop but entering energy-saving operation state, realizes the power saving function that is similar to " frequency conversion " air-conditioning.
In sum, in the embodiment that content of the present invention is not confined to, the knowledgeable people in same area can propose easily other embodiment within technological guidance's thought of the present invention, but this embodiment comprises within the scope of the present invention.
