Problems solved by technology

The kitchen will generate a lot of heat due to cooking activities, causing the internal temperature of the kitchen to be too high, which seriously affects the thermal comfort of the human body
Moreover, a large amount of waste heat generated during the cooking process, if this part of heat energy is not properly recycled, will cause a certain amount of energy waste
At present, the existing kitchen air conditioners on the market are still common vapor compression refrigeration. The difference from ordinary household air conditioners is that they have been treated with anti-oil pollution, but they do not have the effect of recovering kitchen waste heat, and directly use vapor compression refrigeration. The way is to cool the kitchen, with a compressor as a moving part, the system is complicated, and requires additional input of electric energy, which is not energy-saving enough

Embodiment 1

[0028] like figure 1 As shown, the absorption refrigeration kitchen air conditioning system of this embodiment includes a range hood 1, a cooktop 3, a cooker 4, a steam generator 5, a condenser 6, an evaporator 7, an absorber 8, a first heat exchanger 9, The second heat exchanger 10, the third heat exchanger 11, the fourth heat exchanger 12, the water tank 13, the electric heater 14, the solution pump 15, the first throttle valve 17, the second throttle valve 18 and the heat exchanger 19.

[0029] The range hood 1 has a smoke exhaust channel 2 , and a first heat exchanger 9 is installed in the smoke exhaust channel 2 . The cooker 4 is installed on the cooktop 3, the second heat exchanger 10 is installed on the bottom and around the cooker 4, the first heat exchanger 9 and the second heat exchanger 10 are connected in series with each other, and the first heat exchanger 9 can absorb the flue gas The heat generated by the cooker 4 can be absorbed by the second heat exchanger 1...

Embodiment 2

[0037] like Image 6 As shown, in the kitchen air-conditioning system of this embodiment, the capillary wick 16 is installed on the pipeline between the liquid outlet of the absorber 8 and the liquid inlet of the steam generator 5, that is, the capillary wick 16 is used to replace the solution pump in the first embodiment. 15. Realize that the entire refrigeration system has no moving parts. The capillary core 16 is made of porous metal foam with a porosity of more than 90% and a through-porosity of about 97%, or a wire mesh stack, 500-50 mesh, and a pore size of 25-300 μm. The porous capillary wick uses capillary force to transport the solution in the absorber 8 to the vapor generator 5 . The remaining structures and working principles of this embodiment are the same as those of the first embodiment, and will not be described herein again.

[0038] In addition, the air outlet of the air conditioner is not limited to being arranged on the cooktop 3, but can also be arranged ...

Abstract

An absorption refrigeration kitchen air conditioning system comprises a heat exchanger used for absorbing kitchen waste heat and further comprises a steam generator, a condenser, an evaporator and an absorber, a liquid outlet of the absorber is communicated with a liquid inlet of the steam generator, and a steam outlet of the steam generator is communicated with an inlet of the condenser through the heat exchanger. An outlet of the condenser is communicated with an inlet of the evaporator, an outlet of the evaporator is communicated with a first backflow port of the absorber, a second backflow port of the absorber is communicated with a solution outlet of the steam generator, and an air conditioner air outlet communicated with the interior of a kitchen is formed in the position close to the evaporator. The absorption refrigeration kitchen air-conditioning system is applied to kitchen waste heat recovery, heat generated by a cooking range and heat taken away by smoke can be directly used as circulating input power of a refrigeration system, kitchen waste heat is used as a system energy supplement form, waste heat is recovered, electric energy consumption during refrigeration is reduced, and energy conservation and emission reduction are achieved. The system is simple in structure, stable in operation and low in vibration and noise.

Description

technical field [0001] The invention relates to a kitchen air conditioning system, in particular to an absorption refrigeration kitchen air conditioning system. Background technique [0002] The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people have invented various kitchen air conditioners to cool the kitchen air in summer, and provide warm air to the kitchen in winter to improve cooking comfort. Due to the cooking activities in the kitchen, a large amount of heat will be generated, which will cause the internal temperature of the kitchen to be too high, which will seriously affect the thermal comfort of the human body. Moreover, a large amount of waste heat generated by the cooking process will cause a certain amount of energy waste if this part of the heat energy is not pr...
