Removable multi-functional air conditioner

Abstract

The invention relates to a movable multifunctional air conditioner. The bottom part of the air conditioner is provided with idler wheels, and an intermediate valve is arranged in the air conditioner, which leads the space in the air conditioner to be divided into a front chamber and a rear chamber; the front and the rear chambers are provided respectively with an air inlet and an air outlet and an independent fan; the front chamber is provided with a front valve, and the rear chamber is provided with a rear valve; the front chamber provided with an evaporator can produce cold air, and the rear chamber provided with a condenser can produce warm air. By connecting the duct selectively, warm air can be produced in cold days while the cold air is discharged out of the room; conversely, the cold air can be produced in hot days while the warm air is discharged out of the room. Moreover, the front and rear chambers can be communicated through the intermediate valve, which leads the air out of the air conditioner to become dry warm air after dehumidified by the evaporator and then through the condenser, or leads the dry warm air to be sent to the space needing drying, and used for dehumidifying and drying. A heater can be arranged additionally behind the condenser so as to improve the warm air temperature or the drying effect, realizing one machine with multi functions. The invention can be moved to part space needing air-conditioning without the need to work for the whole space so as to save energy source.

At present, the dehumidifiers on the market only have a single purpose of dehumidification and cannot be used for drying. When a dehumidifier is used for dehumidification, the air released by the dehumidifier after dehumidification is dry air with relatively high temperature, low humidity ratio and low relative humidity. It already has quite strong drying capacity; when designing dehumidifiers at home and abroad, the industry often only pays attention to removing part of the moisture contained in the air to reduce the relative humidity of the air; The by-products are not utilized, resulting in a waste of these precious resources that could have been used to dry items; moreover, when dehumidifying on a humid hot day, the relatively high-temperature air discharged by the dehumidifier will heat the space where the dehumidifier is used. In order to achieve dehumidification The purpose is to increase the temperature of the space at the same time; if it is in the humid and hot summer, increasing the temperature will cause discomfort to the human body

Electric hot air dryers and electric heaters have the disadvantages of high temperature, energy consumption and insufficient safety when used

When using a heat pump type cooling and heating machine, the position of the four-way valve must be adjusted to switch between cooling and heating. If the four-way valve is switched during the operation of the cooling and heating machine, the pressure difference between the high and low pressure ends of the system is often ten times the atmospheric pressure. Above, it is easy to cause damage to the switch button of the four-way valve in use and cause failure; when the design of the heat pump air conditioner in the subtropical area is based on air conditioning, based on the principle of heat pump thermodynamics, the heat transfer rate of the condenser must be equal to that of the evaporator. The heat transfer rate is added to the power of the compressor, so the indoor heat exchanger (the evaporator in the air-conditioning function) must be smaller than the outdoor heat exchanger (the condenser in the air-conditioning function) for energy balance, so that the indoor air-conditioning function is normal; but Using the same air conditioner with the same design as the main air conditioner, when the heating function is turned on indoors in cold weather, based on the thermodynamic principle of the heat pump, the indoor heat exchanger (condenser in the heating function) is smaller than the outdoor heat exchanger (in the heating function) can be an evaporator), so it is difficult to meet the energy balance of the thermodynamic principle of the heat pump, so that the heating function is not effective and prone to failure

When heating is the main design of heat pump air conditioners in temperate regions, based on the principle of heat pump thermodynamics, the heat transfer rate of the condenser must be equal to the heat transfer rate of the evaporator plus the power of the compressor, so the indoor heat exchanger (heater) Condenser in function) must be larger than the outdoor heat exchanger (evaporator in heating function) in order to balance energy, so that the indoor heating function is normal; but using the same design as the main heating air conditioner, the indoor air conditioning is turned on on hot days In terms of function, based on the thermodynamic principle of heat pump, the indoor heat exchanger (evaporator in the air-conditioning function) is larger than the outdoor heat exchanger (condenser in the air-conditioning function), so it is difficult to meet the energy balance of the heat pump thermodynamic principle, so that the air-conditioning Poor function, prone to failure

Moreover, the traditional air conditioner or air conditioner must be installed in a fixed place to air-condition the entire space, so the refrigeration tons used need to be large and consume more energy, so the weight is also heavy and it is not easy to move
