Description

Childbirth pig house earth source heat pump floor heating and cooling system
Technical field
The utility model relates to livestock and poultry cultivation facility technology field, relates in particular to a kind of childbirth pig house earth source heat pump floor heating and cooling system.
Background technology
Parturient sow and piglet 1 the product hurdle that coexists in the parturient sow house, and coexist and 1 give up, and sow To Be Protected from Heat; Piglet is afraid of cold; The required environmental temperature higher (28-32 ℃) of piglet in the childbirth pig house, and the environmental temperature that sow needs lower (suitable temperature is 18-22 ℃) are in current Chinese Xia Redong tierra fria; The heat stress that high temperature causes in the childbirth pig house has considerable influence to the reproductive performance of sow, and high temperature is less to the survival rate influence of piglet; The piglet cold stress that the interior low temperature of parturient sow house in winter causes is bigger to the survival rate influence of piglet, and low temperature is not obvious to the reproductive performance influence of sow.The environment conditioning of ubiquity parturient sow house is only paid attention to the heating and the insulation in winter at present; And summer do not taked cooling measure by parturient sow house in most pig farms, only depends on gravity-flow ventilation, first term; For avoiding the piglet window of suffering from cold also to be closed, therefore seldom carry out gravity-flow ventilation.Sow is in the hot environment, and its reproductive performance will be had a strong impact on, like postweaning estrus time retardation or lasting out of heat; The sow feed intake descends and causes lactation amount to descend; Even heat stress can cause when serious antenatal 1 week of sow dead.The winter, the summer environment control that are suitable for sow and piglet temperature in the childbirth pig house simultaneously are comparatively difficult.
Only a few parturient sow house adopts the whole house of wet curtain-blower fan falling temperature technique at present; Wet curtain-blower fan cooling is comparatively effective in the area and the whole house of the period reduction pig house temperature of high temperature low humidity; But will increase humidity in the pig house, and the wind of moist low temperature environment in when reducing the whole house of pig house temperature, giving up and certain speed will be unfavorable to newborn piglet.Also have only a few parturient sow house to adopt the cooling of dripping, drip if do not increase local ventilation equipment in the incidence of sow, cooling-down effect not only increase cost if increase local ventilation equipment, and ventilation equipment takies spatial volume in the pig house in the house with relatively poor.Cooling only reduces sow incidence body temperature and can alleviate heat stress to a certain extent though drip, and it is also indeterminate to the influence degree of reproductive performance that this cooling method is alleviated heat stress to sow.
Be published in and point out in " EI " 2004 the 20th volumes the 1st phase " utilizing underground water " and can couch district's laying cold water pipe to parturient sow local cooling at parturient sow to pig house floor local cooling; But the used underground water of lowering the temperature is extracted out from well and is directly got into pig house; Handle without source pump, not only cooling-down effect is limited, and the water after the cooling circulation recharges; Long-term use will cause that subterranean water level continues to descend in the well, cause anhydrous taking out in the well; And the document does not relate to the way of piglet spot heating.Once put down in writing a kind of facility that adopts the radiation top board for the pig local cooling that grows up in the prior art, the existence meeting of its radiation top board affects to ventilating in giving up, and is inappropriate for the childbirth pig house; Also put down in writing a kind of temperature-control pigsty that circulating water pipe is installed in the prior art under the pig bed, pig riffling spare cool in summer and warm in winter can be provided, but also be the floor heating cooling method that is suitable for adult pig, be inappropriate for the childbirth pig house.Cooling water in the above-mentioned several kinds of data all is phreatic direct utilization; Except that the area of geothermal anomaly; General underground water water temperature only can be used for cooling in summer and can not directly be used for heating, and heating generally need be established the coal-burning boiler heating in addition with hot water, and fire coal will expend primary energy coal; And the generation great amount of carbon dioxide also needs special configuration burning boiler personnel to increase labour cost.Be published in " EI " 2011 27 volumes the 3rd phase " ground source heat pump technology is to the influence of large-scale pig farm energy-saving and emission-reduction " and point out that earth source heat pump is applied in the heating and cooling on pig farm; But in the floor heating design of its pig house, separately do not design the heating and cooling design to piglet with temperature requirements and sow; And directly be connected between earth source heat pump unit and pumped well and the inverted well, underground water directly gets into the earth source heat pump unit, and unit is subject to the groundwater quality influence and phenomenons such as fouling, the obstruction of burn into body refuse occur, thereby increases maintenance cost and reduction of service life.Therefore, the cooling of the floor heating of the pig house of giving a birth at present and floor is the environment conditioning mode of simple function, need to the design of childbirth pig house find a kind of can again can be to the floor heating cooling system of sow cooling in summer to piglet spot heating.
