Description

Technical Field

[0001] This utility model relates to an air conditioning system, and more particularly to a kitchen air conditioning system. Background Technology

[0002] To enhance the cooking experience, air-conditioning range hoods were invented. These add an air conditioning component to the existing range hood platform, combining the functions of a range hood with those of an air conditioner. The compressor, condenser, and evaporator of the air conditioning component are connected via refrigerant piping. Current air-conditioning range hoods employ the following airflow structure: indoor return air enters the evaporator for heat exchange, is cooled, and then blown out by the fan and returned to the room; indoor air is drawn in and enters the condenser for heat exchange, is heated, and then blown out by the cooling fan and enters the flue; the range hood fan draws a portion of indoor air into the cavity and into the flue, which is then exhausted through a common flue. During operation, the continuous supply of kitchen air to the outside, along with the heat exchange in the condenser, creates negative pressure indoors, allowing outdoor air or air from adjacent rooms to seep into the kitchen through doors and windows. Bringing hot air into the kitchen will negatively impact the cooling efficiency of air conditioners and range hoods. Furthermore, because the airflow from the cooling fans and range hood fans is higher than the airflow supplied by the air conditioner, more hot air is drawn into the kitchen than the cool air supplied by the air conditioner, increasing the cooling load on the kitchen and significantly reducing its cooling effect. In areas with severe environmental pollution, outdoor air intake can lower indoor air quality in the kitchen, affecting the health of occupants. Additionally, when the indoor temperature is high, a larger airflow is required to bring the indoor return air to the desired temperature, which will negatively impact the extraction of cooking fumes.

[0003] For example, the Chinese utility model patent "A Kitchen Air Conditioning System" disclosed in patent number 202020844576.7 (authorization announcement number CN 212987510 U) includes a range hood housing with an air outlet duct isolated from the exhaust duct. A fresh air handling unit is installed outside the range hood, and a fresh air duct is formed inside the housing of the fresh air handling unit. The fresh air inlet of the fresh air duct is connected to the outside, and the fresh air outlet is connected to the air inlet of the air outlet duct. The air outlet of the air outlet duct is located on the housing. A first fan is installed in the air outlet duct or fresh air duct to blow the fresh air entering the fresh air duct out of the air outlet of the air outlet duct. When this kitchen air conditioning system is working, outdoor fresh air is processed by the fresh air handling unit outside the range hood and flows into the air outlet duct inside the range hood, and then blown into the kitchen from the air outlet on the housing, providing the kitchen with the required fresh air and greatly improving the user's cooking experience. However, the outdoor fresh air entering the kitchen is not cooled, especially during the hot season when the temperature in the new house is high, which will also increase the cooling load of the air supply and reduce the cooling effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a kitchen air conditioning system that can introduce cooled outdoor fresh air into the kitchen as indoor return air, in view of the above-mentioned existing technology.

[0006] In order to smoothly deliver the cooled fresh air to the indoor unit module, a fresh air fan is installed in the fresh air duct, and the fresh air fan delivers the cooled fresh air to the air inlet of the indoor unit.

[0007] Preferably, the fresh air outlet is connected to the indoor unit's air inlet via an air duct.

[0008] The fresh air treatment module can be installed in multiple different locations. Preferably, the fresh air treatment module is located above the kitchen ceiling, and ventilation holes are opened on the wall above the kitchen ceiling.

[0009] To purify the fresh air, an air valve and a fresh air purification module are installed at the ventilation opening. Additionally, the air valve can be closed when the introduction of outdoor fresh air is stopped.

[0010] To improve the cooling effect of the fresh air, the fresh air treatment module has at least two sets connected in series.

[0011] Further preferably, the fresh air handling module includes a first compressor, a second compressor, a first condenser, a second condenser, and an evaporator, which are connected in sequence via refrigerant pipelines.

[0014] Further preferably, the air conditioning module also includes a compressor assembly, and the compressor assembly, condenser assembly and evaporator assembly are connected by refrigerant pipelines.

[0015] Compared with existing technologies, the advantages of this invention are as follows: This kitchen air conditioning system has a fresh air handling module installed outside the range hood.

This effectively reduces the cooling load caused by the high-temperature supplementary air, thus improving the air conditioning's cooling effect. Furthermore, using outdoor air intake helps balance the indoor and outdoor pressure difference, reducing the infiltration of high-temperature outdoor air into the room through doors and windows, thereby effectively improving the cooling effect.

[0017] Figure 2 This is a schematic diagram of the connection of the air conditioning components according to an embodiment of the present utility model. Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes a range hood 1, which integrates a fume extraction module and an air conditioning module. The fume extraction module includes a fume extraction fan 2, and the air conditioning module includes a compressor assembly 8, an indoor unit module 3, and a heat dissipation module 4. The indoor unit module 3 includes an evaporator assembly 31 and an indoor unit fan 32, and the heat dissipation module 4 includes a condenser assembly 41 and a heat dissipation fan 42. The compressor assembly 8, the condenser assembly 41, and the evaporator assembly 31 are connected via refrigerant piping. The indoor unit module 3 has an indoor unit air inlet 33 and an indoor unit air outlet 34. The indoor unit air outlet 34 is in fluid communication with the interior of the kitchen. The air inlet of the heat dissipation fan 42 is connected to the interior of the kitchen, and the air outlet of the heat dissipation fan 42 is connected to the air inlet of the fume extraction fan 2. The structure of the above-mentioned range hood is the same as that of existing air-conditioning range hoods, and will not be described in detail here. In addition, the air outlet of the cooling fan 42 in this embodiment is connected to the air inlet of the fume extractor 2 through the air guide shroud 43.

[0020] A fresh air handling module 5 is installed externally on the range hood 1. In this embodiment, the fresh air handling module 5 is located above the kitchen ceiling 6, and a ventilation hole 71 is opened on the wall 7 above the kitchen ceiling 6. A damper 56 and a fresh air purification module 57 are installed at the ventilation hole 71. The fresh air handling module 5 can use a pre-filter to filter particulate matter such as PM, and is located downstream of the damper 56. When the air conditioner is turned on, the damper 56 opens, and outdoor fresh air enters the fresh air handling module 5. The fresh air purification module 57 filters the fresh air once, thereby improving the indoor air quality. The fresh air handling module 5 has a fresh air inlet 51 and a fresh air outlet 52. The fresh air inlet 51 is connected to the outside, and the fresh air outlet 52 is connected to the indoor unit air inlet 33 through a duct 55. A filter 9 is installed at the indoor unit air inlet 33. The filter 9 is a high-efficiency filter to perform secondary filtration of the fresh air. The fresh air handling module 5 has a fresh air duct 53 inside, and the fresh air inlet 51 is connected to the fresh air outlet 52 through the fresh air duct 53. A fresh air fan 54 is installed in the fresh air duct 53, and the fresh air fan 54 delivers the cooled fresh air to the indoor unit's air inlet 33. The outdoor fresh air is filtered twice and then blown into the room through the indoor unit's air outlet 34, which helps to minimize the impact on indoor air quality when outdoor air quality is poor.

[0021] The fresh air handling module 5 includes a compressor, a condenser, and an evaporator. In this embodiment, the fresh air handling module 5 has two sets of refrigeration units connected in series, specifically including a first compressor 511, a second compressor 512, a first condenser 513, a second condenser 514, and an evaporator 515. The first compressor 511, the first condenser 513, the evaporator 515, the second compressor 512, the second condenser 514, and the evaporator 515 are connected sequentially through a refrigerant pipeline 516. The evaporator 515 is located in the fresh air duct 53.

[0022] When the kitchen air conditioning system is working, the range hood and air conditioner are turned on simultaneously. Fresh air enters the fresh air duct 53 and flows through the evaporator 515, where it is pre-cooled. Because the fresh air handling unit uses two cooling cycles, it can ensure that the high-temperature outdoor fresh air is fully pre-cooled to the required lower temperature. After being pre-cooled, the fresh air is blown out by the fresh air fan 54, passes through the filter 9, and enters the indoor unit module 3, where it is further cooled. Finally, it is blown out by the indoor unit fan 32 to provide cooling to the kitchen, thereby reducing the heat dissipation airflow requirements of the air conditioner and range hood and avoiding affecting the fume extraction effect.

[0023] The term "fluid connectivity" as used in this utility model refers to the spatial relationship between two components or parts, collectively referred to as the first part and the second part, meaning that a fluid, gas, liquid, or a mixture of both can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, flow guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
