“…Based on the calculation results for the heating panel capacity (Table 1) and physically modeling the heating process for the floor-mounted panel [33] with the application of thermoelectric Peltier elements, and with the account of the data reported in [42,43], an experimental sample of the floor-mounted heating panel power capacity 100 W for prenursery pigs has been manufactured in compliance with the technological block diagram shown in Figure 1. The heating panel operates in the mode of heat pump (Figure 4).…”

Mathematical formulation of the animal thermal status has been developed, with the account of two convenience conditions and heat balance, for the floor-mounted heating panel for prenursery pigs. The borders of the heat flux variation range for the floor-mounted heating panel have been determined corresponding to the animal-friendly conditions for prenursery pigs of various age groups. The block diagram of the energy-saving floor-mounted heating panel, comprising the thermoelectric assembly operating in the heat pump mode, has been designed. The method has been described and the corresponding calculations have been made for the basic thermal parameters of the floor-mounted local heating installation, for prenursery pigs, with the application of a thermoelectric heat pump. The experimental installation sample of 116 W thermal capacity (for the heat transfer coefficient from 0.9 W·m−2·K−1 to 1.0 W·m−2·K−1 and floor temperature in the range of 5 °C to 6 °C) has been developed and manufactured for local heating for prenursery pigs managed in gestation crates. Laboratory tests of the experimental sample of the floor-mounted heating panel have demonstrated high energy efficiency of the heating installation under development. The energy-saving effect (approx. 15% compared to the series-produced equipment designed for local heating of young stock) of the developed installation was achieved owing to the partial heat recuperation of the exhaust ventilating air.

The analysis of local infrared (IR) heaters of young animals with an assessment of their energy efficiency is carried out. Energy saving infra-red heater with regulated heat flow depending on position of animal, for calves, has been designed. The fittings and the reflector of the IR heater allow the use of various heating elements. Electrical circuit diagram of automatic control unit of energy-saving IR heater for prophylactorium period calves, in single penning breeding technology, has been described. The outlay of installation with electric heater has been described and an example of irradiance calculation has been presented. Mathematical expression for calculating irradiance from electric radiant heater, in particular point on the heated surface, has been defined by experiments. It was found that the proposed design and heater control scheme provide a reduction in energy consumption by up to 35% compared to traditional methods of maintaining the temperature in the area where the calves are located.
