Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and temperature regulating devices for breeding farms, in particular to a ventilation and temperature regulating device for pig breeding farms. Background Art

[0002] With the rapid development of modern pig farming, the continuous expansion of breeding scale and the increase in breeding density, the environmental control problem of pig farms has become increasingly prominent. The pig house environment has an important impact on the reproduction, growth and health status of pigs. Ventilation and temperature regulation are the key links of environmental control, and their importance is self-evident.

[0003] Temperatures that are too high or too low can cause stress responses in pigs, which in turn affects their appetite, reproductive performance and immune capacity. For example, in a high temperature environment, pigs will eat less, grow slower, and may even die from heat stroke; while a low temperature environment may increase the pigs' cold stress and induce respiratory diseases.

[0004] In order to provide a suitable breeding environment, corresponding ventilation and temperature control devices are usually installed in pig houses. However, most ventilation and temperature control devices are fans. The fans are used to ventilate and dissipate heat in the pig house to achieve ventilation and cooling effects. However, only fans can be used for ventilation and cooling within a certain range. Heating operations in winter and appropriate cooling operations in summer cannot be performed, which affects the temperature control effect and brings inconvenience to users. In view of this, we propose a ventilation and temperature control device for pig farms. Utility Model Content
