One of the effective methods of reducing energy consumption in systems software technology microclimate of industrial premises with biological objects (livestock, poultry buildings and facilities cultured) in transition and cold season is the use and disposal of excess waste heat vent emissions [1]. Miscarriage air livestock buildings contains a significant amount of heat energy in cultivation facilities (greenhouses) on sunny days comes a significant amount of heat from solar radiation, which causes overheating of the air and plants and leads to the need for "airing" tent greenhouse by removing excess heat through ventilation techniques outside [2,3].

One promising avenue recycling (reusing heat air emissions) is the regeneration of heat in batteries disperse nozzle [4] located, for example in the soil under the building. It is a scientific and practical interest to consider the dynamics of radiation and thermal treatment facilities (for example, greenhouse, as most energy facility) equipped with a forced ventilation system and battery thermal energy in the form of dispersed flow capacity of the completed nozzle.

Perspective is a greenhouse construction (or reconstruction) of the construction of the battery heat. In periods of intense solar radiation to ventilate greenhouses plug fans and excessive heat in the superheated air direct heat accumulator. This allows the heat of day night air tent greenhouses heated by solar energy accumulated. Thus, the need for heat accumulation caused by uneven flow of solar radiation during the day [1].

As short battery storage using heat insulated containers filled with stones (crushed), pebbles, vessels with paraffin, and air piping embedded in the soil under greenhouse [2]. Since accumulation of heat by heat most important parameter is the quantity of heat transmitting surface, the most simple and effective are heat accumulators as a conduit [3] (arbitrary section) filled disperse nozzle (pebbles, gravel, pellets of a substance that has phase transitions, such as melting ). This is a practical and scientific interest to consider the dynamics of radiation and thermal regime greenhouse battery heat, as in [2, 4] considered storage systems miscarriage heat production facilities in stationary mode.

Using the analytical method of research by drawing heat balance equations and their approximate solution of a simplified method for analytical dependences of parameters of air circulating in the system over time, by changing the external thermal receipts Mathematical models of dynamic thermal modes of cultivation facilities equipped with a ventilation system with battery heat.


1. A detailed mathematical model of the radiation and heat treatment facilities with battery cultivation of excess heat.

2. An simplified analytical dependences for determining the daily changes in air temperature in the air volume of the building.
