The present invention aims to solve pedestrian inconvenience caused by freezing or snow accumulation on the walkway during the winter season and to prevent slipping by providing a walkway and a method for installing the same, wherein support blocks made of high-elasticity plastic or rubber are assembled like a puzzle, heating wires are inserted in a straight line into the upper grooves to generate heat, and an aluminum heat dissipation plate with excellent thermal conductivity is placed over them to prevent freezing. During the winter season, when alleyways, school routes, walking paths, market entrances and exits, overpasses, and government office access roads frequently used by pedestrians freeze or snow accumulates, it causes pedestrian inconvenience and poses serious problems such as slipping and injury; therefore, there is a need to prevent freezing of pedestrian walkways and to rapidly melt accumulated snow. Conventionally, to solve the problem of freezing or snow accumulation, methods such as scattering coal ash or calcium chloride on pedestrian walkways or using tools like shovels and hoes to remove frozen areas or snow accumulation require a large amount of manpower, cause environmental damage, and are very cumbersome, and there are various problems such as the fact that they are not completely resolved. Therefore, in order to prevent freezing or snow accumulation on pedestrian walkways during the winter or to melt it quickly, it is very practical to install electric heating walkways that are fast and convenient rather than using de-icing agents that are environmentally harmful and cumbersome to operate. Accordingly, the present invention aims to provide a pedestrian walkway and a method for installing the same, which prevents freezing and snow accumulation by assembling blocks of an elastic material like a puzzle, inserting a heating wire in a straight line into the upper groove to generate heat, and covering them with an aluminum heat dissipation plate having excellent thermal conductivity so that heat generated in the groove of the supporting block, which functions as an insulator, is rapidly conducted through the aluminum heat dissipation plate while using a small amount of electrical energy, thereby allowing the freezing or snow accumulation on the aluminum heat dissipation plate to melt quickly. Furthermore, the present invention aims to provide a pedestrian walkway and a method for installing the same, which promote pedestrian safety by applying a highly visible color with a phosphorescent function during the manufacturing of the aluminum heat sink to enhance convenience for nighttime walking, and by additionally providing a physical function to prevent slipping by imparting uneven grooves to the aluminum heat sink. The prefabricated heated walkway for preventing freezing according to the present invention has the advantage of being installable not only on newly constructed walkways but also on existing asphalt, paved roads, and sidewalk blocks, and can be installed even on uneven roads.

To provide an air conditioning system that can be operated in the appropriate operating mode. [Solution] After stopping operation in heating mode, the control unit 13 issues an instruction to switch the four-way valve 40 to the cooling mode state at predetermined intervals. Even if the air conditioning system 10 remains inactive for a long period of time from the end of the winter season to the start of the summer season after stopping operation in heating mode, the likelihood of the four-way valve 40 switching to cooling mode is increased. This increases the likelihood of reliable operation in cooling mode at the start of the summer season, thereby improving product performance.

A root zone warming system (10) for an athletic field of natural turf (11) supplies positive pressurization to the root zone via a piping network (12) with openings. The system (10) enables control of the temperature of the supplied air by varying the flow resistance at an output end of a constant air supply source (27), such as a positive displacement blower. By increasing the flow resistance at the output end of the blower (27), with a variably controllable valve (29), the operating temperature of the blower (27) increases and thereby causes a corresponding increase in the temperature of the air supplied therefrom. By varying the flow resistance a user can vary the temperature of the air supplied to the piping network (12) and to the root zone, thereby to control the amount of warming of the root zone so as to reduce the onset, degree, or duration of turf dormancy during the winter season.
