The invention belongs to the field of building gutter snow melting systems, and in particular relates to a gutter snow melting system and a snow melting control method thereof. The gutter snow melting system comprises a heat source layer (2) and a temperature control box (4); a protective layer (1) is fixedly assembled outside the heat source layer (2); a port of the heat source layer (2) is connected with a port of the temperature control box (4); a creepage protection layer (4) is fixedly assembled between the heat source layer (2) and the protective layer (1); a port of the creepage protection layer (3) is connected with the port of the temperature control box (4); the protective layer (1) is made of a high polymer material; and the heat source layer (2) adopts a resistant heating plate. The gutter snow melting system has the advantages of light weight, convenience for use, no need of roofing construction, capability of repeated utilization, high automation degree, good snow melting effect and capability of effectively preventing snow water from flowing backwards.

The invention is suitable for a construction method, and discloses a roof snow melting system, which comprises a water storage tank and a circulating pipeline, wherein the water storage tank is buried under the ground; the circulating pipeline is used for conveying water in the water storage tank, and comprises a heating pipe, a heat discharging pipe and a recovery pipe; the heating pipe is used for conveying the water in the water storage tank to a roof; the heat discharging pipe is paved at the roof; the recovery pipe is used for recovering the melted snow water at the roof into the water storage tank; the heating pipe is provided with a multi-stage water pipe heating system for heating water; the heat discharging pipe is provided with a rotary spray head for spraying the hot water. The roof snow melting system has the advantages that the energy-saving and environment-friendly effects are realized, the snow water is recycled and reutilized, the heat energy is sufficiently utilized, the waste of electric energy and heat energy is reduced, the safety and controllability are realized, the snow melting effect of the snow melting system is improved, the technical problem of low utilization rate of resources in the existing snow melting system is solved, and the comprehensive property and market competitiveness of the snow melting system are favorably improved.

A snow melting system for greenhouse comprises sensors for measuring an accumulation of snow on or at the greenhouse. A snow melting processor unit comprises an accumulation rate calculator for calculating an accumulation rate of the snow from the measured accumulation, and a heating prioritizer for actuating at least one of at least two different heating systems of the greenhouse as a function of at least the accumulation rate. A rooftop greenhouse system comprises a greenhouse adapted to be mounted to a rooftop surface. Two or more different heating systems mounted to the greenhouse to heat a roof of the greenhouse, and controlled by the snow melting system.

[Problem] Provided are: an air discharge pipe structure for melting snow on a road surface, the air discharge pipe structure being configured so that the air discharge pipe structure can more evenly discharge snow melting air into an area underneath the road surface on which the snow to be melted is present than conventional structures to prevent the uneven melting of the snow, so that the air discharge pipe structure can be built more easily, and so that the air discharge pipe structure can be built in a reduced time and at reduced cost; a road surface material for melting snow; and a system for melting snow on a road surface. [Solution] An air discharge pipe structure for melting snow on a road surface is provided with: perforated pipes (7, 7, ...) which have air ejection holes (6) formed therein and which are laid in a predetermined area underneath the road surface (5) on which the snow to be melted is present; a pair of connection pipes (8, 8) for air flow, connecting the opposite ends of each of the perforated pipes (7, 7, ...) in a pneumatically communicable manner; and an air supply pipe (9) which connects one end of each of the connection pipes (8, 8) for air flow in a pneumatically communicable manner and which is provided with an air supply opening (11) for supplying air. The other end (81) of each of the pair of connection pipes (8, 8) for air flow is connected to each other in a closed state or is connected to each other by an end air-flow pipe (10) in a pneumatically communicable manner.
