7 Recommended "Spot Coolers" No Construction Needed, Cool and Comfortable Even in Rooms Where Air Conditioning Can't be Installed [2021 Latest Version]

The "Spot Cooler" is a device that uses the same "heat exchange" method as ordinary air conditioners to send out cold air, unlike fans and circulators. Room air conditioners are divided into an indoor unit and an outdoor unit, but the image of a spot cooler is that these are integrated. It does not require an outdoor unit and does not need to be fixed and installed, so it can be placed in various places without construction work. With casters, it is easy to move around the house.

The mechanism is the same as a compressor type dehumidifier. For this reason, most spot coolers also have a dehumidifying function, which is useful in damp seasons and for drying laundry indoors.

By the way, there is a "reifusen" as a home appliance that emits cold air, but this is a home appliance that uses the heat of vaporization of water to send out cold air. The spot cooler introduced here is something else that has a completely different principle.

The advantage of a spot cooler is that it can be placed anywhere, but it is important to note that it also emits cold air and heat (usually from the back). Just like the image of "an air conditioner's indoor unit and outdoor unit integrated", this is unavoidable in principle.

For this reason, it is necessary to be careful because the room temperature will actually rise if the cool air operation is continued without releasing the waste heat to the outside in a closed room. The manufacturer of the spot cooler also explains to that effect.

Many models come with an air duct (hose) attached to the back. In many cases, the heat can escape to the outside through the duct. Some models come with a panel that allows you to attach the duct to the window frame, which effectively reduces the room temperature by exhausting heat to the outside. Let's check it according to the room and installation environment to be used.

Cooling capacity is indicated in "kW" (kilowatts). For home use, the standard is about 2 kW to 2.2 kW, which can cover a room of about 6 tatami mats. Even with the same model, the cooling capacity differs depending on the electric frequency, and it is higher in the 60Hz area than in the 50Hz area (power consumption also increases).

It depends on the model, but even a standard model requires about 8 to 9A (amperes) of electricity. Make sure the breaker doesn't trip when you use it.

Water (drain water) is generated inside the spot cooler. It has the same mechanism as a compressor-type dehumidifier, but there is a "non-drain" type model that evaporates water inside the spot cooler and eliminates the need for wastewater treatment.

However , When using in a room with high humidity even for non-drain type, water may accumulate in the tank before treatment can be completed in time. In this case, it is necessary to dispose of it manually. Some models, which are mainly for dehumidification, are equipped with removable large-capacity tanks to reduce the frequency of drainage work.

In addition, the operating sound of the spot cooler is relatively loud. This is because room air conditioners have a built-in compressor installed in the outdoor unit. If you want to use it in quiet situations, such as when you go to bed, check the volume while driving.

A remote control, an exhaust duct, and a panel to attach the duct to the window are included. In the 2021 model, the window panel is a shutter type, and even when not in use, you can prevent outside air from entering by closing the shutter without removing the panel. In addition, an auxiliary key is included and can be attached to the inside of the window to secure the window and window panel.

The size is 286 (width) x 320 (depth) x 700 (height) mm, and the weight is about 22 kg. It also comes with casters for easy movement.

Cooling capacity (50Hz/60Hz): 2.0kW/2.2kW

A stylish design model of Iris Ohyama's "portable cooler". It has a standard cooling capacity and is said to be compatible with rooms of 4.5 to 7 tatami mats. It is a "non-drain" type that evaporates drain water inside. Power consumption is 490W (50Hz)/600W (60Hz).

If you attach the attached duct to the cold air vent, you can freely change the direction of the airflow, and if you attach it to the heat exhaust vent, you can release the exhaust heat to the outside. Drain water accumulates inside, but when the tank is full, it switches from cold air operation to fan operation, and the indicator light flashes to indicate that it is full.

Corona's Dokodemo Cooler, a major manufacturer of air conditioners, claims to function as a clothes dryer and dehumidifier in addition to cooling air. Model.
