A wireless transceiver module is disposed on the electronic control board 106 and/or in the second housing 201, for wireless communication with a remote control. The cold standby temperature threshold can be set by the remote controller, and when the temperature sensor detects that the temperature of the water tank 107 reaches the cold standby temperature threshold, the cold standby state is stopped, the operation of the water pump 108 and the compressor 103 is stopped, and the cold standby state is entered. The portable air conditioner has a normal working state, in a cold-feeding standby state, the driving water pump 108 and the blowing fan 203 are started first, the interval between 0.2-2 seconds, the compressor 103 and the condensing fan 109 are started, so that the portable air conditioner enters the normal working state, at this time, the blowing fan 203 blows cold air to cool the inner space of a temporary building where the indoor air conditioner unit 2 is located, and the cold air and water both form a circulation. The standby cooling temperature threshold is set to 9 ℃, the water outlet temperature of the host unit 1 is about 4 ℃, and the water outlet temperature of the host unit 1 is about 7 ℃ because the standby cooling temperature threshold is an initial state of a normal working state of the portable air conditioner, the cooling load is higher, the water return temperature can be gradually increased, and after a period of time of operation, the water return temperature is stabilized at about 12 ℃. The portable air conditioner also has a mute working state and is used for people to sleep in the temporary building. The frequency of the compressor 103 is reduced, the temperature of the water in the water tank 107 is controlled to be in the range of 9-17 degrees celsius, and the blower fan 203 is operated using the lowest power gear or the second to last power gear. And when the temperature of the water in the water tank 107 is below 10 degrees celsius, the compressor 103 and the condensing fan 109 are not turned on until the driving water pump 108 and the blowing fan 203 are turned on.

In some exemplary embodiments, in order to maintain cooling for a long time, the portable air conditioner further has the following structure: firstly, the outside of the water inlet connecting pipe 3 and the outside of the water return connecting pipe 4 are wrapped with heat preservation layers or heat preservation pipes, the heat preservation pipes are soft and bendable, and the heat preservation pipes are fixed on the outside of the water inlet connecting pipe 3 and the outside of the water return connecting pipe 4 through bonding layers or pressing pieces. Secondly, the water tank 107 is of a heat preservation water tank structure, the water tank 107 is externally wrapped with a heat preservation layer, and the water tank 107 is made of materials with poor heat conductivity. The third is that be provided with the ice-cube standing groove on the lateral wall of first casing 101, but be provided with the ice-cube standing box of the double-deck vacuum insulation structure that pull out in this ice-cube standing groove, when going out, the ice-cube has been placed in the ice-cube standing box, so when this portable air conditioner uses, can place the box with the ice-cube earlier and take out, in adding the water tank 107 with the ice-cube in the ice-cube standing box, with the temperature in reducing water tank 107, so can directly skip and send cold standby state, and the initial state that the cold load is higher when portable air conditioner normal operating condition, also can not need to start compressor 103, so make the use of battery 111's electric quantity can be longer. Fourthly, a plugging and installing structure such as a cannula is arranged on the side wall of the first shell 101, and a sunshade device can be plugged and installed in the plugging and installing structure.

In some exemplary embodiments, the first housing 101 is further provided with a light sensor, where the light sensor is electrically connected to the electric control board 106 and the driving water pump 108 of the refrigerant circulation system, the light sensor is used for detecting the light intensity in the external environment, a weak light threshold value and a strong light threshold value are provided in the electric control board 106, and when the light sensor detects that the light intensity in the external environment is changed by the weak light threshold value and the strong light threshold value, the electric control board 106 automatically increases the detection temperature of the water in the water tank 107, thereby increasing the temperature of the wind blown by the indoor air conditioning unit 2, and enabling the user to wake naturally.

In some exemplary embodiments, a water receiving tray and a condensate pump are further disposed in the second housing 201, the water receiving tray being located at a lower end of the water-air heat exchanger 202, the water receiving tray being for receiving and storing condensate water generated when air flows through the water-air heat exchanger 202. The condensate pump is arranged at the low concave part of the water receiving disc. A condensate drain pipe is connected to the condensate pump, which is connected to the first chamber, the second chamber of the water-air heat exchanger 202 or to the return water connection pipe 4 through a tee. The water collector lower surface is provided with the heat preservation, and the water collector is provided with the overflow hole, and this overflow hole dismantles and is connected with the overflow pipe.

The portable air conditioner has the advantages that: the refrigerant supplied to the indoor air conditioning unit 2 is cold water, which is supplied to the indoor air conditioning unit 2 through a hose, and the hose reduces noise. Compared with the refrigerant directly serving as the refrigerant, the indoor air conditioner unit 2 is high in safety, is placed in a temporary building for use, leaks in the temporary building, seriously harms the physical health of people due to the fact that the refrigerant leaks into the temporary building, and the cold water leaks with lighter consequences. Secondly, the refrigerant is not suitable for being conveyed by a hose with vibration reduction and noise reduction effects, and is easy to leak. Thirdly, if a hard pipe such as a copper pipe is used to convey the refrigerant, the use of the connection host unit 1 and the indoor air conditioning unit 2 is inconvenient, which results in inconvenient use of the portable air conditioner. And fourthly, the refrigerant is used for cooling, and the refrigerant entering the water-air heat exchanger 202 has three states of gas state, gas-liquid coexisting state and liquid state, so that the heat exchange effect of the refrigerant in the gas state and the gas-liquid coexisting state is poor. Therefore, the cooling is performed by using cold water, so that the heat exchange efficiency can be effectively improved, and the service life of the battery 111 can be effectively prolonged. Meanwhile, the volume of the water-air heat exchanger 202 can be reduced, so that the size of the indoor air conditioning unit 2 is effectively reduced, and the indoor air conditioning unit 2 is more convenient to carry.
