Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to a multifunctional heat recovery energy-saving device for an animal room. Background Art

[0002] Heat recovery is a unit that recovers heat sources. It has a high calorific value and is often used in pharmaceutical factories, animal rooms and other places with a lot of heat sources and heating and energy-saving needs. The heat recovery mechanism is to transfer the indoor heat in summer to the circulating water. The water temperature becomes higher, and a heat recovery unit is installed on the return water pipeline. The air-conditioning return water flows into the above-mentioned unit to bring out the indoor heat for the unit to make hot water. After cooling, it flows into the air-conditioning related units, which reduces the power consumption of the air-conditioning unit to make cold water and avoids the disorderly loss of heat.

[0003] The existing traditional three-effect heat recovery device has exhaust humidification turned on in both summer and winter. In fact, in summer, the fresh air heat energy should be recovered for dehumidification and reheating, while in winter, the exhaust heat energy should be mainly used. There is no need to turn on exhaust humidification, which not only wastes resources, but also reduces the energy saving and heat recovery effects. Therefore, we need to propose a multifunctional heat recovery and energy-saving device for animal rooms. Utility Model Content

[0016] Compared with the prior art, the multifunctional heat recovery and energy-saving device for animal rooms described in the utility model has the following beneficial effects:

[0017] 1. The utility model is provided with an exhaust mechanism, a connecting mechanism and a fresh air mechanism. When used in summer, the temperature of the air entering the fresh air box is lower than the temperature of the air discharged from the exhaust box. Then, heat exchange is performed by the exhaust mechanism and the fresh air mechanism, so that the temperature of the air discharged from the exhaust box can be lowered, and the air in the exhaust box can be pre-cooled. In winter, the temperature of the air discharged from the exhaust box is higher than the temperature of the air entering the fresh air box.

[0018] 2. The utility model is provided with a circulation component, a water outlet pipe, a long pipe and a return pipe. In winter, since the exhaust air temperature is higher than the temperature of the circulating water, there is a temperature difference between the air and the water. Therefore, when the exhaust air flows through the exhaust coil, the heat in the exhaust air is transferred to the circulating water. Therefore, the exhaust air temperature is reduced and the water temperature is increased. At this time, since the temperature of the circulating water is higher than the inlet temperature of the fresh air, the water transfers the heat obtained from the exhaust air to the fresh air, and the temperature of the fresh air is increased due to the heat. In summer, the process flow is the same, but the direction of heat transfer is opposite. The liquid is generally water. In severe cold and cold areas, in order to prevent frost and ice, an ethylene glycol aqueous solution should be used, and different concentrations should be selected according to the local outdoor temperature and the freezing point of ethylene glycol.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] like Figure 1-8As shown: a multifunctional heat recovery and energy-saving device for an animal room, comprising an exhaust mechanism 1, a connecting mechanism 2 and a fresh air mechanism 3, wherein the exhaust mechanism 1 is arranged at the top of the connecting mechanism 2, and the fresh air mechanism 3 is arranged at the bottom of the connecting mechanism 2, the exhaust mechanism 1 comprises an exhaust box 11 and an exhaust coil 12, the exhaust coil 12 is fixedly installed in the inner cavity of the exhaust box 11, a circulation component 13 for circulating the liquid inside the exhaust coil 12 is arranged on the top of the exhaust box 11, an exhaust component 14 for exhausting air is arranged in the inner cavity of the exhaust box 11, and the fresh air mechanism 3 comprises a fresh air box 31 and a fresh air coil 32, the fresh air coil 32 is fixedly installed in the inner cavity of the fresh air box 31, and the inner cavity of the fresh air box 31 is provided with a fresh air component 33 for suctioning air;

[0035] Through the arrangement of the exhaust mechanism 1, the connecting mechanism 2 and the fresh air mechanism 3, when used in summer, the temperature of the air entering the fresh air box 31 is lower than the temperature of the air discharged from the exhaust box 11, and then heat exchange is performed through the exhaust mechanism 1 and the fresh air mechanism 3, so that the temperature of the air discharged from the exhaust box 11 can be lowered, and the air in the exhaust box 11 can be pre-cooled; in winter, the temperature of the air discharged from the exhaust box 11 is higher than the temperature of the air entering the fresh air box 31, and then heat exchange is performed through the exhaust mechanism 1 and the fresh air mechanism 3, so that the air entering the fresh air box 31 can be preheated, thereby avoiding the situation where the fresh air coil 32 handles excessive low-temperature load.

At this time, since the temperature of the circulating water is higher than the inlet temperature of the fresh air, the water transfers the heat obtained from the exhaust air to the fresh air, and the temperature of the fresh air increases due to the heat. In summer, the process is the same, but the direction of heat transfer is opposite. The liquid is generally water.
