[0002] With the development of society and the economy, people are living in high-rise buildings and using air conditioners. An air conditioner, also known as an air conditioner, is a device that manually adjusts and controls the temperature, humidity, flow rate, and other parameters of the ambient air within a building or structure. The main types of air conditioners include cabinet units, wall-mounted units, water-cooled units, window units (half indoor and half outdoor), central units, and two-in-one units (one outdoor unit controls two indoor units). To achieve rapid cooling, the air conditioner compressor typically requires high power.

[0017] The following will combine the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the present invention. Figure 1-2 As shown, a stand-alone air conditioner includes a chassis 1, a controller 2 disposed within the chassis 1, a refrigeration system 5, and a heat exchange system 3. The controller 2 is electrically connected to the refrigeration system 5 and the heat exchange system 3. The chassis 1 includes an indoor portion and an outdoor portion. A heat exchange air inlet 1.1 and a heat exchange air outlet 1.2 are disposed at the rear and front of the indoor portion, respectively. The heat exchange system 3 includes a heat exchanger 3.1 disposed within the chassis 1 and located in front of the heat exchanger air inlet 1.1. A heat exchange fluid storage tank 3.10 is disposed within the chassis 1 to store antifreeze heat exchange fluid 3.11. A heat exchange fluid circulator 3.9 is disposed within the heat exchange fluid storage tank 3.10 to provide circulation power. A heat exchange fluid circulation pipe 3.8 connects the heat exchange fluid storage tank 3.10, the heat exchanger 3.1, and the heat exchange fluid circulator 3.9 to form a liquid circulation loop. The evaporator 5.1 of the refrigeration system 5 is sealed within the heat exchange fluid storage tank 3.10. For the indoor part, the rear is the side close to the wall, and the front is the side relatively far from the wall. The heat exchange liquid circulator 3.9 here can be a pump body. The heat exchange liquid 3.11 is filled in the heat exchange liquid storage tank 3.10 connected to the heat exchange liquid circulation pipe 3.8 and the heat exchanger 3.1 and the heat exchange liquid circulator 3.9 to form a liquid circulation loop. The heat exchange liquid 3.11 can be an antifreeze liquid with a relatively large specific heat capacity that can withstand freezing above -30°C. The utility model uses antifreeze liquid as the heat exchange liquid 3.11. The antifreeze liquid can store a large amount of cold energy. After the refrigeration system 5 stops refrigeration, the antifreeze liquid can still continue to make the single-unit air conditioner blow out cold air through the heat exchange system. The utility model reduces the power required by the compressor of the refrigeration system. Using refrigerator compressors and other refrigeration methods can meet the requirements.

[0018] The indoor and outdoor portions of the housing 1 are integrally mounted or removably connected, and the housing 1 is inserted through an aperture in a wall of a house. The wall of the house may include a conventional wall, a curtain wall, or a structure such as glass that separates the indoor and outdoor portions of the house. The housing 1 of the present invention is a single, integrated structure, offering a simple design, compact and rational arrangement of various components, a small overall size, and minimal material loss. Alternatively, the housing 1 can be installed separately, with the indoor and outdoor units installed separately, as in the prior art.

[0019] The indoor part and the outdoor part are threadedly connected, and an inner and outer isolation sealer 1.3 is provided at the connection between the indoor part and the outdoor part to allow pipes to pass through. The inner and outer isolation sealer 1.3 can be foam glue, and pipes or other components that need to extend from the indoor part to the outdoor part need to pass through the inner and outer isolation sealer.

[0020] The refrigeration system 5 includes an evaporator 5.1 sealed within a heat exchange fluid storage tank 3.10, a compressor 5.3 located indoors, a condenser 5.5 located outdoors, and a condenser cooling fan 5.6. A capillary tube 5.4 connects the condenser 5.5 and the evaporator 5.1, with the other ends of both the evaporator 5.1 and the condenser 5.5 connected to the compressor 5.3. Therefore, the outdoor portion of the chassis 1 is provided with a condenser cooling air inlet 1.4 and a condenser cooling air outlet 1.5. The evaporator 5.1 is sealed and fixed within the heat exchange fluid storage tank 3.10, with seals installed at the inlet and outlet, employing conventional sealing methods. The compressor 5.3 can be fixedly mounted at the bottom of the chassis 1, with refrigerant 5.2 contained within the refrigeration cycle formed by the evaporator 5.1, condenser 5.5, capillary tube 5.4, and compressor 5.3. The condenser 5.5 and condenser cooling fan 5.6 are adapted to be fixedly mounted outdoors in the chassis 1 to facilitate heat dissipation. The condenser cooling fan 5.6 is arranged on the outside of the condenser 5.5.

[0021] The heat exchange system 3 also includes an air-conditioning fan 3.2 arranged in front of the heat exchanger 3.1, and an air deflector 3.3 fixed to the heat exchange outlet 1.2 is arranged in front of the air-conditioning fan 3.2; a condensation water collector 3.4 is fixedly arranged below the heat exchanger 3.1, and one end of a condensation water pipe 3.5 is connected to the condensation water collector 3.4 and the other end is connected to the condensation water atomizer 3.7 below. The lower part of the condensation water atomizer 3.7 is connected to a condensation water spray pipe 3.7 with one end extending to the outdoor part.

[0022] The heat exchange liquid storage tank 3.10 is fixedly provided with an electric auxiliary heater 4 on its outer surface or internally provided, and the electric auxiliary heater 4 is electrically connected to the controller 2. The liquid inside the heat exchange liquid storage tank 3.10 can also be heated by other electric heating mechanisms.

[0023] The chassis also includes a fresh air system 6, comprising an air filter positioned below the heat exchange inlet 1.1, a fresh air blower 6.2 positioned below the air filter, and a fresh air inlet duct 6.1 mounted on the fresh air blower 6.2. The other end of the fresh air inlet duct 6.1 extends outdoors. A fresh air filter element 6.3 can be positioned within the air filter to isolate indoor and outdoor air within the fresh air system. The fresh air blower 6.2 is electrically connected to the controller 2.

[0024] Controller 2 is adapted to be fixedly mounted within the chassis. It is electrically connected to a plurality of electrical appliances, including the air conditioning fan 3.2, air deflector 3.3, condensate atomizer 3.6, heat exchange fluid circulator 3.9, electric auxiliary heater 4, compressor 5.3, condenser cooling fan 5.6, and fresh air blower 6.2. Controller 2 controls the operation of the heat exchange system 3, electric auxiliary heater 4, refrigeration system 5, and fresh air system 6 according to the indoor air environment, regulating the indoor air heating, cooling, and fresh air exchange to achieve the air temperature and freshness level set by controller 2.

[0025] The power source of the present invention can be mains electricity or photovoltaic panels and batteries. During operation, simply connect the power cord and activate the controller to select various functions, including cooling and dehumidification, heating, and fresh air. This utility model offers low power consumption, low noise, a simple structure, compact and rational arrangement of various devices, a small overall size, and minimal material loss. It combines multiple functions, including fan, cooling, heating, fresh air, and dehumidification.

[0026] When working, turn on the power and turn on the controller 2 to select various functional modes such as cooling, heating, and fresh air.

[0027] In heating mode, controller 2 controls components such as the electric auxiliary heater 4, air conditioning fan 3.2, air deflector 3.3, and heat exchange fluid circulator 3.9 to generate heat. During heating, under the control of controller 2, electric auxiliary heater 4 first activates to store heat. This heats heat exchange fluid 3.11. Once the temperature of heat exchange fluid 3.11 reaches the set temperature and a certain amount of heat energy is stored, controller 2 activates the air conditioning fan 3.2, air deflector 3.3, and heat exchange fluid circulator 3.9. Driven by heat exchanger circulator 3.9, heat exchanger fluid 3.2 circulates through heat exchanger circulation pipe 3.8, heat exchanger 3.1, and heat exchanger storage tank 3.9, transferring heat energy to heat exchanger 3.1. Air conditioning fan 3.2 draws indoor air in through heat exchanger inlet 1.1, where it releases heat and heats up. After being directed by air deflector 3.3, the hot air is blown out of heat exchanger outlet 1.2 into the room, initiating continuous air conditioning and heating. When the indoor air reaches a preset temperature, electric auxiliary heater 4, under the control of controller 2, continues to store heat, heating heat exchanger fluid 3.11. Once heat exchanger fluid 3.11 reaches the set temperature and stores a certain amount of heat energy, electric auxiliary heater 4 stops heating heat exchanger fluid 3.11. When the indoor air temperature drops and lowers the temperature of heat exchange fluid 3.11 to the set temperature, electric auxiliary heater 4, under the control of controller 2, turns on again to store heat. Electric auxiliary heater 4 heats heat exchange fluid 3.11. When the temperature of heat exchange fluid 3.11 reaches the set temperature, after storing a certain amount of heat energy, electric auxiliary heater 4 stops heating heat exchange fluid 3.11. This process is repeated continuously under the control of controller 2 to complete the heating and control of the air in the room.

[0028] Controller 2 sets the indoor air temperature. It coordinates the operation of electrical appliances such as the air conditioning fan 3.2, air deflector 3.3, heat exchange fluid circulator 3.9, compressor 5.3, and condenser cooling fan 5.6. During cooling, the refrigeration system 5, consisting of the evaporator 5.1, refrigerant 5.2, compressor 5.3, capillary tube 5.4, condenser 5.5, and condenser cooling fan 5.6, starts up under the control of controller 2 to store cold energy. Compressor 5.3 starts to compress refrigerant 5.2, raising the temperature of condenser 5.5. Condenser cooling fan 5.6, under the control of controller 2, starts to draw ambient outdoor air through condenser cooling inlet 1.3 to dissipate heat for condenser 5.5. The outdoor air then absorbs heat from condenser 5.5 and is discharged through condenser cooling outlet 1.4. The temperature of evaporator 5.1 drops, chilling heat exchange fluid 3.11 in heat exchange fluid storage tank 3.10. Once the temperature of heat exchange fluid 3.11 drops to the air conditioning start-up setpoint temperature (e.g., 5°C) set by controller 2, air conditioning fan 3.2, air deflector 3.3, and heat exchange fluid circulator 3.9 activate the air conditioning cooling operation. Heat exchange fluid circulator 3.9 pushes the low-temperature heat exchange fluid 3.11 in heat exchange fluid storage tank 3.9 through heat exchange fluid circulation pipe 3.8, into heat exchanger 3.1, and circulates back to heat exchange fluid storage tank 3.10. Air conditioning fan 3.2 draws indoor air in through heat exchange inlet 1.1. Heat exchanger 3.1 absorbs heat and cools the air. The cool air then flows through air deflector 3.3 and is blown into the room through heat exchange outlet 1.2, beginning continuous cooling operation. During the cooling process, condensed water from heat exchanger 3.1 collects in condensate collector 3.4 and then flows through condensate pipe 3.5 to condensate atomizer 3.6. After being atomized, the condensed water is sprayed onto condenser 5.5 via condensate spray pipe 3.7, cleaning and cooling condenser 5.5 and achieving energy conservation. When the indoor air temperature drops to the minimum temperature set by controller 2, heat exchange fluid circulator 3.9, under the control of controller 2, stops operating. Refrigeration system 5 continues to operate, chilling heat exchange fluid 3.11 and storing cold energy. After heat exchange fluid 3.11 cools to the controller's set temperature (e.g., -20°C), storing a certain amount of cold energy, refrigeration system 5 stops operating under the control of controller 2. When the indoor air temperature rises to the maximum temperature set by controller 2, heat exchange fluid circulator 3.9 and refrigeration system 5 restart under the control of controller 2. This process repeats continuously under the control of controller 2 to complete the air cooling control in the room.

[0029] In the fresh air mode, controller 2 controls fresh air blower 6.2 to perform fresh air exchange. When in operation, controller 2 controls fresh air blower 6.2 to draw fresh air from outside through fresh air inlet pipe 6.1 and blow it into the room through air filter 3.1. When the indoor air reaches the set standard, the blower stops working.

[0030] The fresh air mode can be operated simultaneously with the cooling mode or the heating mode.

[0031] The technical features of the above-described embodiments may be combined in any manner, and as long as there are no contradictions in the combination of these technical features, they shall be deemed to be within the scope of this specification. Without departing from the overall concept of the present invention, the technical solutions of the present invention, their equivalent replacements or modifications, and certain changes and improvements made thereto shall also be deemed to be within the scope of protection of the present invention.
