Description
Technical field
The utility model relates to air-conditioner device technical field, particularly relates to a kind of air conditioner room unit.
Background technology
Winter of severe cold area due to outdoor temperature very low, and off-premises station is blown a cold wind over to outdoor, and what cause low-temperature receiver to distribute is relatively slow, directly can affect compression mechanism hot merit and imitate, make the heating efficiency of indoor apparatus of air conditioner very slow.Therefore, often can increase the auxiliary heat of electricity in current indoor apparatus of air conditioner and wait equipment.
The auxiliary heat of electricity, refers to PTC (Positive Temperature Coefficient, positive temperature coefficient) the electric auxiliary thermal technology of air-conditioning, and being exactly in theory increases heating capacity with extra electrical heating, can be obviously better in effect.PTC is wherein a kind of semiconductor heating pottery, and when ambient temperature reduces, the resistance value of PTC reduces thereupon, caloric value can correspondingly increase on the contrary, refer to that a kind of material has PTC effect definitely, i.e. positive temperature coefficient effect, only refer to that the resistance of this material can increase with the rising of temperature.
According to above-mentioned principle, have employed the air-conditioning of the auxiliary thermal technology of PTC electricity, automatically can change caloric value according to the change of room temperature and the size of indoor set air quantity, thus regulate indoor temperature rightly, reach rapid, the powerful object heated.In general, cold weather has a strong impact on the normal performance of air conditioner refrigerating heat-production functions, and with the auxiliary hot merit of electricity can air-conditioning, because the auxiliary heat of electricity is to the adjustment of air-conditioning caloric value, booster action, then overcome this shortcoming well, very applicable severe cold area uses.
In the air conditioner room unit of existing electric auxiliary heat 7 as shown in Figure 1, electricity auxiliary hot 7 is placed between blower fan 4 and evaporimeter 6, when air conditioner heat-production, auxiliary hot 7 surface temperatures of in running order electricity reach 200 ° to 400 °, the air that blower fan 4 exports first is heated to form high temperature gas flow through hyperthermal electricity auxiliary hot 7, then again heat through hyperthermal evaporimeter 6 (surface temperature 50 ° to 70 °), if the gas flow temperature after auxiliary hot 7 heating of electricity and evaporimeter 6 temperature contrast is little or also high than evaporimeter 6 temperature time, the efficiency of air-flow secondary heat exchange is not high, even heat exchange efficiency can be reduced.It is unreasonable that air-conditioner internal structure is arranged, and can cause energy efficiency of air conditioner lower.
In the air conditioner room unit of existing electric auxiliary heat 7 as shown in Figure 2, electricity auxiliary hot 7 is placed between evaporimeter 6 and air outlet 5, and electricity auxiliary hot 7 is in the tip of V-type evaporimeter 6.The efficiency that this structure can eliminate the air-flow secondary heat exchange of the air conditioner room unit of the existing electric auxiliary heat 7 of Fig. 1 is not high, even can reduce the problem of heat exchange efficiency.But the tip due to evaporimeter 6 is just upper and lower heat exchanger junction, copper pipe and fin closeer, the air ratio flowed through herein is less, when air-conditioner is in heating condition, actual participation electricity auxiliary hot 7 heat-shifts air body product fewer, heat exchange efficiency is low.Simultaneously because electricity auxiliary hot 7 is placed on the tip of V-type evaporimeter 6, from air outlet 5 and panel closer, auxiliary hot 7 temperature of electricity are very high, easily by roasting for panel distortion, aging, even fire, or child touches electricity auxiliary hot 7 and can scald; Electricity auxiliary hot 7 itself is electric conductor, and people touches entail dangers to personal safety.
In the air conditioner room unit of existing electric auxiliary heat 7 as shown in Figure 3, electricity auxiliary hot 7 is placed between evaporimeter 6 and air outlet 5, and electricity auxiliary hot 7 in V-type evaporimeter 6 Lower Half near drip tray place.The air body product that this structure solves auxiliary hot 7 heat-shifts of actual participation electricity is fewer, the problem that heat exchange efficiency is low.But and unresolved due to electricity auxiliary hot 7 be placed on from air outlet 5 and panel closer, electric auxiliary hot temperature degree is very high, easily by roasting for panel distortion, aging, even fire, or child touches electricity auxiliary hot 7 and can scald; Electricity auxiliary hot 7 itself is electric conductor, and people touches entail dangers to personal safety; Drip tray has water and accumulates when spring and autumn colds and heat succeed each other, electricity auxiliary hot 7 powers on and easily causes the problem of machine electric leakage.
