Problems solved by technology

Due to the large temperature difference between winter and summer in most parts of my country, and the simultaneous existence of high temperature and high humidity in summer, environmental control is relatively difficult.
In summer, even if tunnel ventilation, wet curtain cooling, spray cooling and other means are used, the problem of high temperature and high humidity cannot be solved at the same time in summer (that is, wet curtain and spray can cool down through evaporation, but greatly increase the relative humidity. ); in winter, due to the high price of natural gas in my country, the operating cost of existing gas heating equipment is also high
[0003] Therefore, there is a lack of a low-cost pig house operation system and operation method that can simultaneously reduce temperature and remove humidity in China

Abstract

The invention discloses a precise ventilation system using a heat pump and a ventilation pipe in a pig house and an operation method. According to the system, the heat pump is used as a power source for cooling and heating in the hog house and is matched with the ventilation pipe to accurately supply air into the hog house, through ventilation strategies at different temperatures, the humidity can be reduced while the temperature is controlled in summer, the hog house can be heated with lower cost in winter, the ventilation energy consumption is reduced, and the energy consumption of the hog house is reduced. The comfort level of the pig house environment is greatly improved, and the production performance is improved.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and breeding facilities, and specifically relates to a precise ventilation system and an operation method using a heat pump and a ventilation pipe in a pig house. Background technique [0002] Good environmental control is very important to sow and boar performance. Because of the suitable climate conditions in the main pig-raising developed countries abroad, the environmental control is relatively easy. Due to the large temperature difference between winter and summer in most parts of my country, and the simultaneous existence of high temperature and high humidity in summer, environmental control is relatively difficult. In summer, even if tunnel ventilation, wet curtain cooling, spray cooling and other means are used, the problem of high temperature and high humidity cannot be solved at the same time in summer (that is, wet curtain and spray can cool down through evaporation, but great...
