Background technique

With the development of social economy and the change of people's life philosophy and the bad influence of environmental weather, the demand for clothes dryers is increasing year by year. The clothes dryers currently on the market are usually electric heating drum type, which use electric heaters to heat the air, and the hot air absorbs the moisture in the clothes and then is discharged from the air outlet. This kind of clothes dryer generally consumes a lot of energy, and the energy utilization rate is low. Does not meet the requirements for energy saving and emission reduction. Also have a kind of heat pump type clothes dryer, the cooling capacity that its evaporator produces is not utilized, causes waste.

In addition, the normal operation of the existing hotels requires a drying system, a freezer, and a domestic hot water system. At present, these systems are three independent systems, with high energy consumption, large volume, and complex systems, especially the freezer. The heat of condensation generated has not been effectively utilized at all, therefore, it is particularly necessary to design and develop a three-in-one device.

The device is mainly composed of an ordinary mobile air conditioner and a foldable drying container, and there is no hot water utilization and refrigeration. Features.

It can be seen from the above public documents that the existing inventions are all composed of ordinary heat pump air conditioners and different drying boxes, and there is no design and development of an air conditioner that can meet the requirements of hotel drying from the perspective of energy saving, emission reduction and full utilization of resources. Clothes, domestic hot water, refrigeration and freezing integrated multi-functional device cannot effectively meet the needs of hotels and other places for continuous domestic hot water, refrigeration and refrigeration and other large and medium-sized cold storage, as well as low-consumption, high-efficiency and compact drying requirements for sheets and towels. integrated device. Therefore the present invention just adopts new thinking and new structural form. In view of the fact that the cooling capacity or heat of the ordinary heat pump air-conditioning system has not been effectively utilized at all, and at the same time these places need medium and large-scale cold storage equipment and other practical needs, the present invention develops a three-in-one device with better energy saving and emission reduction Wait for the effect.

Contents of the invention

The technical problem to be solved in the present invention is to design an integrated device that can meet the multi-functional requirements of hotel drying, domestic hot water, refrigeration and freezing, etc. in view of the shortcomings of the existing heat pump type clothes drying device, and provide a The integrated device of high-efficiency refrigeration and freezing, domestic hot water, and drying of clothes and beddings makes full use of the heat pump cycle to efficiently dry clothes and produce domestic hot water during intermittent working hours. The heat generated is recovered and utilized, and the production of domestic hot water or the drying process of clothes has been completed at the same time.

Theoretical basis of the present invention: the freezing and refrigerating cold storages of hotels and restaurants mostly realize their refrigerating and refrigerating functions by a vapor compression refrigeration cycle, which uses low-temperature and low-pressure refrigerants to evaporate and refrigerate, and uses liquids with a very low vaporization temperature as refrigerants to make them work under low pressure and mechanical control. Evaporate and absorb heat to achieve the purpose of cooling. While the refrigeration equipment is cooling, it is necessary, especially its own condenser, to transmit and dissipate this part of the cooling load and the power consumed by the compressor to the atmosphere. Traditional cold storage equipment The condensing heat of the cold storage has not been utilized at all, and at the same time, hotels and hotels need to use boilers to produce domestic hot water, and use electric heating dryers to dry clothes and bedding, so that in fact, the waste heat of cold storage heat has not been utilized at all , while hot water and drying clothes will consume more energy alone. This invention uses the heat pump effect to utilize the waste heat generated by the cold storage which is much larger than its own power consumption. By combining the refrigeration of the cold storage with the drying of the heat pump, a new type of hot water freezing and refrigeration device for drying clothes is designed, and the heat pump is further integrated. The cooling capacity and domestic waste hot water in the hotel are used, so that users can use the cooling function while using the dry hot water function, which can not only reduce the operating cost of the hotel cold storage/drying system, but also realize the integration of drying, hot water and freezing, and improve life. Quality; It can also achieve the effect of drying and preparing domestic hot water at low cost, which greatly improves the actual utilization efficiency of the equipment, and at the same time helps to reduce greenhouse gas emissions and achieve energy saving and emission reduction.

Its working principle is further explained as follows: (1) Refrigeration cycle refers to that the high-pressure refrigerant vapor discharged from the compressor is cooled in the condenser, then flows through the throttle valve, and expands adiabatically, so that the temperature of the refrigerant vapor is further reduced. The cold energy is released in the evaporator to achieve the cooling effect. The working principle of the refrigeration cycle is the same as that of the heat pump cycle, but its main purpose is to use the cooling capacity generated on the evaporator in the heat pump cycle. (2) Air circulation, the high-pressure refrigerant vapor discharged from the compressor flows into the condenser, the latent heat released when the refrigerant vapor condenses heats the air in the pipeline, and the air exchanges heat through the condenser to become hot air and blows it into the dry cabinet, The air circulating in the drying cabinet contacts the surface of the clothes, and the hot air driven by the fan continuously evaporates and absorbs the moisture in the clothes. Then the humid air carrying moisture is filtered by the fiber filter and then enters the evaporator to release heat. The temperature drops below the corresponding dew point temperature, and the water vapor in it condenses into small water droplets and drips into the water receiving tray. The air then enters the condenser again to complete a cycle. After the clothes are dried, the system automatically turns on the ultraviolet sterilization to disinfect the clothes to ensure the clothes are clean and hygienic. At the same time, a large amount of domestic waste water discharged in the life process of hotels and hotels is used to cool the hot air, replacing the original position of the evaporator, so as to make better use of the cooling capacity in the evaporator and save part of the energy consumed by additional cooling. (3) The domestic hot water preparation cycle, the high-pressure refrigerant vapor discharged from the compressor of the refrigeration unit flows into the shell-and-tube or sleeve-type condenser, and the latent heat released by the refrigerant vapor during condensation heats the water in the pipeline and sends it into the domestic heat The water storage tank meets the needs of hotel and hotel life.

The technical solution adopted in the present invention: the three-in-one integrated device for clothes drying and hot water freezing in the hotel includes a freezing and refrigeration unit, a domestic hot water preparation unit and a clothes drying unit.

The three-in-one integrated device includes three major cycles: refrigeration cycle, hot air cycle and domestic hot water cycle. The circuit outlet solenoid valve 11 and the selection control of the compressor exhaust and drying circuit solenoid valve 15 ensure the alternate work of air circulation or domestic hot water circulation.

The refrigerating and refrigerating unit in the integrated device includes a refrigerating unit and a freezing unit, and the evaporator used can be an air-cooled evaporator or a direct-cooled evaporator, and also includes a necessary insulation layer for a common refrigerating and freezing device. Control system, air duct system and other conventional configurations.

The domestic hot water preparation unit in the integrated device adopts a shell-and-tube condenser, or a casing condenser, and other similar condensers, so as to realize the difference between the heat of condensation and the domestic hot water when the refrigeration unit is working. The heat exchange between them directly realizes the guaranteed supply of domestic hot water.

The clothes drying unit in the integrated device is composed of an air-cooled condenser, a clothes drying box and a clothes disinfection device, and the clothes drying box can adopt a conventional drying box mode.

The domestic hot water preparation unit and the clothes drying unit in the integrated device can work at the same time, or can work separately, which needs to be adjusted according to the size of the load, and the control system and solenoid valve configured in the system control the discharge of the compressor. High temperature and high pressure refrigerant flow direction.

The air circulation includes a drying cabinet, a fiber filter, an air-water heat exchanger, a fan, and is connected with pipes.

The refrigerating cycle includes an evaporator, a condenser, a compressor, a throttle valve, and auxiliary devices, which are connected by pipelines.

The air-water heat exchanger is provided with a waste water inlet pipe and a three-way valve.

The three-way valve has two branches, the a branch discharges the water, and the b branch connects the water to the condenser.

In the air circulation, there is a fiber filter behind the drying cabinet, and the blast air from the fan flows into the drying cabinet from the air inlet pipe and then flows out from the pipe with the fiber filter.

An ultraviolet disinfection device is housed in the dry cabinet.

The example device of the all-in-one machine is an all-in-one drying and freezing machine in which the branch b of the three-way valve is closed, and the domestic wastewater is discharged through the branch a after cooling the air, or a branch a of the three-way valve is closed, and the domestic wastewater passes through the branch b A freezer that cools the condenser.

The three-in-one device fully considers that the refrigeration and refrigeration equipment of hotels needs to ensure the freezing and refrigeration effect continuously for 24 hours a day, and at the same time, the drying system of hotels and hotels does not need to run continuously for 24 hours a day, so that it can While ensuring the effect of refrigeration and refrigeration, fully utilize the condensation waste heat generated by refrigeration and refrigeration to supplement domestic hot water and dry clothes and bedding, etc., to achieve the goal of killing multiple birds with one stone, save energy to the greatest extent, and reduce the operating costs of hotels and hotels.

Beneficial effects of the present invention: the present invention makes full use of theoretical basis such as refrigerating and heat pump cycles, so that the waste heat generated by refrigerating and refrigerating equipment in hotels can directly drive the domestic hot water preparation system and the clothes drying cycle device, so that the refrigerating system of the vapor compression refrigerating system The energy and heat have been effectively used, which greatly reduces the energy consumption of hotels and hotels. And compared with the traditional cold storage, dry clothes and hot water supply system, the present invention has the advantages of simple structure, convenient processing and installation, and low maintenance cost in the later stage.

In conjunction with accompanying drawing 3, the specific implementation manner of the integrated device for drying clothes, hot water and freezing in a hotel is further described in detail. As shown in accompanying drawing 2, this all-in-one machine for drying and freezing is composed of a freezing system, a control panel and a drying system. Domestic waste water is used as an auxiliary cooler to cool and dry the hot and humid air blown from the drying cabinet. At the same time, a three-way valve is used, and two working conditions are considered, so as to ensure that the refrigeration cycle will not be affected even if the drying cycle is stagnant. normal work.

As shown in Figure 2, when the drying cycle is running normally, the b branch of the three-way valve 22 of the drying unit is closed, and the domestic wastewater is discharged through the a branch of the three-way valve 22 of the drying unit after cooling the air; when the drying cycle is stagnant At this time, the a branch of the three-way valve 22 of the clothes drying unit is closed, and the domestic wastewater passes through the b branch of the three-way valve 22 of the clothes drying unit to directly cool the condenser, and the refrigeration cycle works normally at this time.

When the air circulation is running normally, the b branch of the three-way valve 22 of the drying unit is closed, and the domestic wastewater is discharged through the a branch of the three-way valve 22 of the drying unit after cooling the air; when the air circulation is stagnant, the three-way valve of the drying unit The branch a of 22 is closed, and the domestic waste water directly cools the condenser through the branch b of the three-way valve 22 of the clothes drying unit, and the refrigeration cycle works normally at this time. The all-in-one machine uses a heat pump to provide heat, and utilizes the remaining cold capacity of the evaporator in the refrigeration cycle, and uses domestic wastewater instead of the evaporator to cool the air in the air cycle, which greatly improves energy utilization efficiency, saves power, saves space, and is easy to use convenient.

At the same time, we also need to consider that when the domestic wastewater is used to cool the humid hot air, the same drying effect can be achieved. In the air circulation, driven by the fan, the hot and humid air passing through the clothes is first cooled by the domestic waste water in the auxiliary cooler to realize the cooling and dehumidification process. That is: the dry bulb temperature t of the air decreases, and at the same time, the water vapor carried in the air condenses into water on the surface of the evaporator, and the absolute moisture content d decreases; the cooled and dehumidified air passes through the condenser to achieve isohumidity and temperature rise. That is: the dry bulb temperature t of the air rises, the absolute moisture content d remains unchanged, and the relative humidity decreases; the high-temperature and low-humidity air blown out from the condenser flows through the clothes, isenthalpic humidification and cooling, and then returns to the evaporator to restart the cycle .

The scope of application of the present invention is not limited to hotels, and can be widely applied to similar places such as hotels and fast food restaurants.
