Description
Technical Field
The utility model relates to an energy-conserving technical field of air conditioner specifically is an air conditioner waste heat recovery utilizes system for providing steam in kitchen.
Background
As known to those skilled in the art, the "refrigeration" is not only a simple cooling process, but in contrast to natural cooling, the "refrigeration" process is actually a process of transferring heat from a "low temperature heat source" to a "high temperature heat source" by consuming a certain amount of external energy (such as electric energy, heat energy, solar energy, etc.). Therefore, the temperature of the refrigerating medium is reduced by refrigeration, and the heat converted by external work is added, so that the heat larger than the cold is necessarily generated. At present, in most air conditioner designs, the heat is not utilized, and power of a water pump and a fan is consumed, so that the heat is taken away by cooling media (water, air and the like) through a condenser.
The refrigeration cycle mainly comprises four basic components, namely a compressor, a condenser, an expansion valve and an evaporator. The refrigerant continuously circulates in the system, changes state and exchanges heat with the outside.
After absorbing the heat of the object to be cooled in the evaporator, the liquid refrigerant is vaporized into low-temperature and low-pressure steam, sucked by the compressor, compressed into high-pressure and high-temperature steam, discharged into the condenser, released into a cooling medium (water or air) in the condenser, condensed into high-pressure liquid, throttled into low-pressure and low-temperature refrigerant by the expansion valve, and enters the evaporator again to absorb heat and vaporize, thereby achieving the purpose of circulating refrigeration. Thus, the refrigerant is subjected to four basic processes of evaporation, compression, condensation and throttling in the system to complete a refrigeration cycle.
In a refrigeration system, an evaporator, a condenser, a compressor and an expansion valve are four major pieces indispensable in the refrigeration system, among which the evaporator is a device that delivers cooling energy. The refrigerant absorbs heat from the cooled object therein to perform cooling. The compressor is a heart and functions to suck, compress, and deliver refrigerant vapor. The condenser is a heat-emitting device, which transfers the heat absorbed in the evaporator to a cooling medium together with the heat converted by the compressor. The expansion valve performs throttling and pressure reducing functions on the refrigerant, simultaneously controls and regulates the amount of refrigerant liquid flowing into the evaporator, and divides the system into a high-pressure side and a low-pressure side. In addition to the four major components, some auxiliary devices, such as solenoid valves, distributors, dryers, heat collectors, fusible plugs, pressure controllers, etc., are often provided in the actual refrigeration system to improve the economy, reliability and safety of operation.
After the refrigerant is compressed by the compressor, heat carried by the refrigerant enters the condenser, and the heat is condensation heat. The condensation heat includes heat absorbed by the chilled water from the room, heat generated by the compressor motor and the refrigerant compressed, and friction heat generated by the high-speed flow of the gas refrigerant in the pipeline. Therefore, the heat of condensation is greater than the cooling capacity.
As is known, a refrigerating machine needs to discharge a large amount of condensation heat during operation, and operates under the working condition of an air conditioner, the refrigerating capacity is 3-5 times of the power consumption, and the condensation heat is 4-6 times of the power consumption. If the refrigerator operates at high condensing temperature, the refrigerating capacity is 2.5-4 times of the power consumption, and the condensing heat is 3.5-5 times of the power consumption and reaches 1.2-1.3 times of the refrigerating capacity. The excessive running of the water chilling units raises the ambient temperature around the building, and causes serious environmental pollution. Moreover, due to the rise of the ambient temperature, the working environment of the water chilling unit is also deteriorated, so that the COP of the unit is reduced, and the energy consumption of the air conditioner is increased.
At present, the main energy consumption of a kitchen is the power consumption of an air conditioner and the oil consumption of a hot water boiler, and the kitchen has the advantages of high energy consumption, high cost, high water consumption and lower production efficiency. The air-conditioning waste heat recovery system is used for replacing a boiler to supply steam, so that the energy of the air-conditioning system can be comprehensively utilized, and the energy consumption of a user is greatly reduced.
