Described one-piece air conditioner device, the both sides of described air-valve are provided with heat-insulation layer, conduct the loss of refrigeration capacity that is brought to reduce the heat that takes place by air-valve between indoor air intake and the outdoor air intake.Lead at the indoor and outdoor air inlet on the stream of evaporimeter and condenser, also be provided with removable filter net (11), (12), with the dust and the foreign material filtering of air intake.

By controller (21) control air-valve motor (22) action, can drive switch air-valve (43) rotate switch turnover distinguished and admirable to.When switching air-valve (43) and be in as shown in Figure 1 first state, indoor air inlet one (44) communicates with indoor air outlet (461), (462) and (463), room air is under the effect of evaporator fan (41), enter evaporimeter air channel (49) from indoor air inlet one (44), through flowing into indoor from indoor air outlet (461), (462) and (463) behind the evaporimeter.Outdoor air enters aircondition from outdoor air inlet (47) under the effect of condenser fan (42), flow to outdoor through behind the condenser from outdoor air outlet (48).When switching air-valve (43) and be in as shown in Figure 2 second state, indoor air inlet one (44) communicates with outdoor air outlet (48), and outdoor air inlet (47) communicates with indoor air outlet (461), (462) and (463).

Indoor air inlet two (45) is provided with the air door (451) that can open and close, and communicates with outdoor air outlet (48).Can drive the motion of indoor air inlet two air doors (451) by controller (21), control the switching of indoor air inlet two (45).When indoor air inlet two (45) was opened, room air can enter aircondition from indoor air inlet two (45) under the effect of condenser fan (42), arranged to outdoor from outdoor air outlet (48).

As shown in Figure 4, the refrigeration system (3) of the one-piece air conditioner device of present embodiment description comprises compressor (31), condenser (32), throttle part (33), evaporimeter (34) and auxiliary piping.Evaporimeter (34) bending be " " shape, and vertically lay.

Throttle part (33) is connected in parallel and is formed by the be stressed auxiliary throttle part of control of a main capillary (331) and, and this auxiliary throttle part is composed in series by unloader (332) and assisted capillary (333).Unloader (332) is opened when pressure is higher than setting Ps, and assisted capillary (333) conducting this moment descends system exhaust pressure; When system pressure recovers just often, unloader (332) cuts out automatically, not conducting of assisted capillary (333).This auxiliary throttle system that has unloader can efficiently move system in specified environment, also can normally freeze in hot environment, avoids shutting down because of compressor protection.

Described one-piece air conditioner device has compression refrigeration, hybrid refrigeration and changes three kinds of mode of operations of wind refrigeration.

During according to the compression refrigeration mode operation, switching air-valve (43) is in first state as shown in Figure 1, and the air door (451) of indoor air inlet two (45) is closed, and compressor (31), evaporator fan motor (23) and condenser fan motor (24) leave.Room air flows into from indoor air inlet one (46) under the effect of evaporator fan (41), the cold-producing medium interior by evaporimeter air channel (49) guiding and evaporimeter (34) carries out heat exchange, and the air after being cooled is discharged to the indoor from indoor air outlet (461), (462) and (463).Outdoor air flows into from outdoor air inlet (47) under the effect of condenser fan (42), carries out heat exchange with condenser (32), and the air after the heat absorption is discharged outdoor by outdoor air outlet (48).

During according to the hybrid refrigeration mode operation, switch air-valve (43) and be in first state, but the air door (451) of indoor air inlet two (45) opens, compressor (31), evaporator fan motor (23) and condenser fan motor (24) leave.Be that with the difference of compression refrigeration pattern room air also enters aircondition by indoor air inlet two (45), under the effect of condenser fan (42), arrange to outdoor from outdoor air outlet (48).

According to changing wind refrigeration mode when operation, switch air-valve (43) and be in as shown in Figure 2 second state, the air door (451) of indoor air inlet two (45) is opened, and compressor (31) stops, and evaporator fan motor (23) and condenser fan motor (24) are opened.Outdoor air flows into from outdoor air inlet (47) under the effect of evaporator fan (41), is discharged to the indoor from indoor air outlet (461), (462) and (463) by evaporimeter air channel (49) guiding.Room air flows into from indoor air inlet one (44) under the effect of condenser fan (42), discharges outdoor by outdoor air outlet (48).

Test shows, the package AC plant of certain specified refrigerating capacity 7500W, and the air quantity of indoor evaporator fan is per hour about 750 cubic metres during the compression refrigeration operation.Changing wind refrigeration mode when operation, indoorly per hour be about about 850 cubic metres to outdoor air output.When 27 ℃/19 ℃ of 12 ℃/10 ℃ of outdoor dry bulb and wet bulb, indoor wet and dry bulb temperature, change the refrigerating capacity that wind just can reach about 7400W by indoor and outdoor is two-way, can satisfy the needs that freeze fully.Therefore the one-piece air conditioner device of present embodiment description under the condition that still needs under the outdoor low temperature environment indoor refrigeration, can replace the compression refrigerating system operation to come to the indoor cold that provides by changing the wind refrigeration system.

The control method one of described one-piece air conditioner device may further comprise the steps:

1) design temperature Ts, dTs.Ts is the design temperature of aircondition start operation, can be by the user by button, remote controller or long-range setting.When indoor EAT was higher than Ts, air-conditioner moved indoor refrigeration.DTs is the setting temperature difference of judging that the refrigeration system operational mode is switched, generally sets when air-conditioner is made.Reach DTs when above when outdoor temperature is lower than indoor temperature, air-conditioner transfers two-way energy saver mode operation of changing wind to.

2) particularly,,, and the temperature signal that is detected is sent to controller by the external air inlet temperature T e of outdoor temperature sensor sensing chamber by EAT Ti in the indoor temperature transmitter sensing chamber.
