Problems solved by technology

[0005] At present, due to restrictions on initial investment and operation, pig houses usually adopt a large factory-style breeding method, which cannot provide suitable temperature and humidity environments for pigs at different growth stages. Environmental temperature and humidity regulation puts forward higher technical requirements

Abstract

The invention relates to a pig farm temperature and humidity automatic adjusting system applying a ground source heat pump technology, and belongs to the technical field of livestock and poultry breeding facilities. The pig farm temperature and humidity automatic adjusting system applying the ground source heat pump technology comprises a heat pump unit and a U-shaped buried heat exchange pipe. The buried heat exchange pipe is communicated with the input end of the heat pump unit through a first circulating pipeline; and a circulating refrigerant pipeline of the heat pump unit is used for exchanging heat with a second circulating pipeline of a newborn piglet area, a third circulating pipeline of a weaning piglet area, and a fourth circulating pipeline of a pig fattening area. The pig farmtemperature and humidity automatic adjusting system applying the ground source heat pump technology has the beneficial effects that heating piglets in winter and cooling the piglets in summer are achieved through a ground source heat pump; energy-saving and environment-friendly automatic temperature and humidity adjustment is realized; and a U-shaped buried heat exchange pipeline technology does not destroy an underground water system.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding facilities, and in particular relates to an automatic temperature and humidity adjustment system for pig farms using ground source heat pump technology. Background technique [0002] Different growth stages of pigs have different requirements on the temperature and humidity of the environment, which will affect the disease probability, feed conversion rate, pork quality, etc. of pigs, and directly affect the economic interests of farmers. [0003] Pigs have different somatosensory critical temperatures at different growth stages. The critical temperature for newborn piglets is 32-35°C, for weaned piglets is 25-29°C, for fattening pigs is 15-25°C, and the lower limit for adult pigs is 12°C. Pigs are in a suitable temperature environment during their growth, which is conducive to their healthy growth. The influence of the lower limit critical temperature on pig production: fo...
