Description
Technical Field
The utility model relates to a facility technical field is bred to beasts and birds, specifically is about a distributed air conditioning system of beasts and birds house.
Background
Environmental parameters such as air temperature, humidity, wind speed, pollutant concentration and the like in the livestock and poultry house are very important to animal health and production performance, and an air conditioning system is usually adopted to ensure that the environmental parameters in the house are in a proper range, including a summer cooling system, a winter heating system and the like. In summer, the most widely used cooling system of the livestock and poultry house is a wet curtain-fan cooling system, and because the wet curtains in the system are intensively arranged on a gable wall on one side of the livestock and poultry house, the problem of uneven distribution of environmental parameters in the house is caused, for example, the temperature difference between a wet curtain end and a fan end is large. In winter, because heating equipment such as a boiler, a heat pump and the like has higher cost and operating cost, livestock and poultry houses do not usually heat, so that the problems of cold stress, uneven temperature distribution and the like of animals are easy to occur. Therefore, the research on the low-cost livestock and poultry house air conditioning system which has the functions of cooling and heating and can improve the distribution uniformity of environmental parameters in the house is of great significance and is a future development trend.
In recent years, heat recovery systems have been developed and applied to livestock and poultry houses to a certain extent, and the systems recycle waste heat of exhaust air to heat fresh air, so that the temperature in the houses is increased, and the heating cost is reduced. Therefore, effectively combining the heat recovery system and the cooling system may be a way to solve the problems of the current air conditioning system for the poultry house. Patent CN201621091214.5 discloses an integrated environmental regulation system for different seasons of livestock and poultry houses, which is basically described as: the system comprises a wet curtain-fan cooling system, an energy-saving heat recovery ventilation system and an automatic control system. However, the traditional wet curtain-fan cooling system is adopted in the patent, the wet curtain is still intensively arranged on one side gable wall of the livestock and poultry house, and the temperature difference in the livestock and poultry house is easy to be large in summer. In addition, the energy-saving heat recovery ventilation system is also intensively arranged at one end of the livestock and poultry house, and can heat fresh air but not uniformly supply air in winter. It is known that although this patent has both cooling and heating functions and is not expensive, the problem of uneven distribution of environmental parameters in the house still exists due to the centralized arrangement of the air conditioning system.
The distribution of environmental parameters in the livestock and poultry house is not uniform, and the problems of local cold stress in summer, local heat stress in winter, poor air quality and the like are easily caused, so that the growth, the health and the production performance of livestock and poultry are greatly influenced. Therefore, an energy-saving and efficient air conditioning system is needed to be further designed to realize the uniform distribution of environmental parameters in the livestock and poultry house and avoid the problems of local cold and heat stress and the like, so that the healthy growth of animals is guaranteed and the production efficiency is improved.
