All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Fig. 1 schematically shows the structure of a snow-proof ventilation system of an air-source heat pump unit in an embodiment of the present utility model. The snow-proof ventilation system of the air source heat pump unit in this embodiment as shown in fig. 1 includes a forced ventilation device and a snow-proof device.
In this embodiment, as shown in fig. 1, the heat pump unit includes three heat pump outdoor units 10, specifically, air source heat pump outdoor units, which may be arranged in one or more rows at intervals, and of course, each row may also be multiple. The air outlets of the heat pump outdoor units 10 are all located at the top, and each heat pump outdoor unit 10 adopts an air outlet mode of an ejector air, and is uniformly arranged as the ejector air, so that ventilation can be facilitated. The utility model aims at the heat pump unit arranged outdoors, and is provided with the snow-proof device and the forced ventilation device, thereby ensuring the efficient and stable operation of each heat pump outdoor unit in the heat pump unit.
As described in the background art, the present inventors have recognized that when a heat pump unit heats water by a heat pump, air discharged from each heat pump outdoor unit 10 is cool, and cool air having a high density is sunk and accumulated around the heat pump outdoor unit 10 after being blown out, which results in a decrease in the suction temperature of the heat pump, thereby decreasing the efficiency of the heat pump; based on the above, the forced ventilation device is configured for the heat pump unit, and cold air can be effectively discharged by adopting the forced ventilation device and is discharged out of the arrangement range far away from the heat pump unit, so that the problem that the air inlet temperature is influenced and the heat pump efficiency is influenced due to sinking and accumulation of cold air discharged by the heat pump outdoor unit 10 is avoided. In the present utility model, compared with the conventional heat pump outdoor units which exhaust air independently and naturally through the top air outlet, the forced ventilation is called forced ventilation because the fan 23 is used to uniformly exhaust and exhaust the cold air collected in the air duct 22.
As shown in fig. 1, in this embodiment, the forced ventilation device includes a suction hood 21, an air duct 22 and a fan 23 for guiding all the cool air discharged from each heat pump outdoor unit 10 to the outside of the arrangement range of the heat pump units. The air outlet at the top of each heat pump outdoor unit 10 is provided with an air suction cover 21, and all the air suction covers 21 can be connected to the same air duct 22 to collect cool air uniformly, but the utility model is not limited thereto. In addition, the air duct 22 is also connected with a fan 23, and as shown in fig. 1, a fan 23 may be installed at the end of the air duct 22. Further, the inlet end of the fan 23 is connected with the air pipe 22, and a filter screen is arranged to prevent the fan 23 from being interfered by larger sundries, and the outlet end is directly connected with the atmosphere. In addition, the tail end of the air pipe 22 is arranged far from the arrangement range of the heat pump unit, and the other end of the air pipe 22 is closed, so that the fan 23 can perform forced ventilation operation.
In addition, as shown in fig. 1, the air duct 22 is arranged above the heat pump unit in a transverse arrangement mode, and the transverse arrangement of the air duct 22 is more beneficial to cold air discharge; the arrangement is reasonable, and the actual running and operation are not influenced; the air duct 22 is transversely arranged above the heat pump unit, so that a certain distance is formed between the air duct 22 and the heat pump unit in the height direction, and the influence of the low-temperature air duct wall on the ambient temperature of the heat pump unit is avoided to a certain extent.
In this embodiment, the air suction cover 21 has a narrow cavity and a wide cavity, the narrow cavity is inserted into the air duct 22 and sealed with the air duct 22, and the wide cavity is installed at the air outlet in a buckling manner and sealed, so as to ensure that cold air completely enters the air duct 22. By adopting the structure, cold air of the heat pump outdoor unit 10 can be effectively pumped into the air pipe 22, the forced ventilation efficiency is improved, and the cold air is prevented from sinking and accumulating around the heat pump unit to the greatest extent. Of course, the suction hood 21 and the air duct 22 may be integrally formed to ensure the sealing effect of the suction hood 21 and the air duct 22. Furthermore, the narrow-mouth cavity can be cylindrical or prismatic, the wide-mouth cavity is conical, the small caliber is connected with the narrow-mouth cavity, the top surface of the wide-mouth cavity can be cambered surface, three-sided conical, four-sided conical and the like, and the conical wide-mouth cavity can better play a role in caching cold air.
As shown in fig. 1, in this embodiment, the ceiling 31 of the snow protection device is installed above the heat pump unit to protect the main unit, and is located above the forced ventilation device, and the area of the ceiling 31 covers the whole heat pump unit, so as to prevent frost from forming in the main unit of the heat pump outdoor unit 10 due to snowflake floating, and thus the efficiency of the heat pump unit is affected. In addition, the snow protection device further comprises a plurality of upright posts 32, the ceiling 31 can be supported and arranged through the plurality of upright posts 32, as shown in fig. 1, the upright posts 32 are arranged on the periphery of the heat pump unit, the ceiling 31 is fixed with the tops of the upright posts 32, the edge of the ceiling 31 extends out of the upright posts 32, and further one side can extend out of the tail end of the air pipe 22.
In addition, the air duct 22 is also fixed to the snow guard, for example, the air duct 22 may be fixed to the upright post 32, so that the support for the forced ventilation device may be provided by the snow guard, and the stability of the air duct 22 during ventilation may be improved. As shown in fig. 1, the distal end of the ductwork 22 may be secured to the upper portion of the upright 32 while ensuring that the ductwork 22 is laterally disposed.
