Solar Swine Systems for Ohio – An Update

Posted in: Energy by admin on January 1, 1981 | No Comments

Solar systems vary widely in their cost and performance. Although pork producers are in an ideal position to use solar energy, there is no guarantee a solar system will pay off. You must select the right system for the right application, watch construction costs, operate and maintain it correctly.
Conservation pays, with or without solar technology. Insulation, lower ventilation rates, efficient zone heating and (or) cooling, and temperature and draft control are essential to profitable confinement hog production.

Controlled Environment Swine Housing and Energy Conservation

Posted in: Energy by admin on | No Comments

The merits of controlled environment swine housing in our climates are well accepted. A controlled environment facility requires three interrelated components:
1) insulated building
2) ventilation system
3) supplementary heat
In each of these there are specific areas in which improvements in general practice will help to reduce heat loss and improve energy efficiency. This article examines the above three components in detail using diagrams, tables and practical examples.

Saving Energy in Swine Buildings

Posted in: Energy by admin on January 1, 1980 | No Comments

There are many ways to save energy in a swine building and it’s important to consider all of them. Usually the ventilation system will offer the biggest and most economical opportunity for saving fuel. While trying to cut energy costs don’t forget that the ultimate goals are comfort for the hogs and profits for the swine producers.

Waste Heat Recovery in Piggeries

The report describes the construction of a heat exchanger using relatively inexpensive and corrosion resistant materials. Computer simulation of the heat exchanger performance in a typical pig finishing house is also described. Laboratory experiments on the heat exchangers’ performance indicated an effectiveness in the order of 40%. The computer simulation uses this value, hourly weather data for one year and typical data for a finishing house for its calculations. The simulation calculates the reduction in additional feed costs due to house temperatures below the critical, when a heat exchanger system is incorporated. The paper shows how the value taken for minimum ventilation rate determines the economic viability and need for heat recovery.

Minimizing Fossil Fuel Usage in Swine Facilities

Posted in: Energy by admin on | No Comments

The most cost-effective way to conserve fossil fuel is to manage the ventilation system. Recognition of the several purposes of ventilation with controls to accommodate these functions, promotes good management and reduces fuel usage. Conservation equipment and renewable energy sources require additional expenditure, thus reducing cost effectiveness.

Heat-Saving Solutions Control Energy Costs

In the future, fuel costs are expected to increase 6-10% each year. Previously, during periods of relatively inexpensive fuel costs, producers have not been reluctant to heat farrowing and nursery buildings to 80F and some even up to 90F. Today, with high fuel costs, many producers are looking for ways to reduce these increasing costs. If the winter fuel costs are extremely high in your farrowing or nursery building, check your winter ventilation rate. Provide a small heated and protected sleeping area for the small pigs and lower the room temperature. Insulating the walls and ceilings which lowers their surface temperature, even when the air temperature remains the same, has a marked effect on the newborn pigs total heat loss rate. Baby pigs are very sensitive to drafts that humans can hardly detect. Natural ventilation is energy efficient compared to conventional ventilation equipment. Natural ventilation is strongly recommended for most grower-finishing units during the summer. Ventilation maintenance has an impact on energy efficiency.
