I. Overview of the program
Gardening greenhouses refer to cultivation sites such as flowers, vegetables, and fruit trees. In winter, the outdoor temperature is very low. In order to provide a suitable environment for flowers and vegetables, it is necessary to use a gardening heater to warm the greenhouse. This solution overcomes the limitation of greenhouse heating in greenhouses and significantly improves the heating of greenhouses. The effect solves the conversion from static heat dissipation to flow heat dissipation mode, which greatly reduces the humidity in the greenhouse. The power of the heater drives the air to circulate continuously. After the heating of the heater, the air in the greenhouse sterilizes. The role of sterilization.
Second, the selection
According to the hot medium used for heating in horticultural greenhouses, it is 60-80 °C low-temperature hot water. It is recommended to use our YLS-1 horticultural heaters;
The horticultural heater is mainly composed of a high-efficiency air heater and an outer-rotor fan. The air heater dissipates heat, and then the fan sends out, so that the indoor air temperature can be adjusted. The air heater is composed of a copper tube and a heat-dissipating aluminum sheet through a tube-expanding process. It is 1.0mm, the pipe and the heat medium circulation pipe are the whole welded structure, and the test pressure of the radiator of the heater is higher than 0.8MPa.
YLS heater
Third, examples
On-site parameters: The heat medium is 70 ° C hot water, used for planting greenhouse heating, the greenhouse length is 144m wide and 88m high 5m, the outdoor temperature is -20 °C, and the temperature in the shed is required to reach 15 °C. The joint greenhouse greenhouse has a total of 11 spans, each span is 8m.
solution:
(1) Determine the heater model
According to the hot water and use of 70 ° C using the heat medium, it is determined to use the YLS-1 type garden heater.
(2) Determine the number of heaters
The heating area of ​​a single YLS-1 gardening heater is 180m2, the heating area of ​​the greenhouse is 144*88=12672m2, the number of heaters is 12672/180=70.4, and 70 units are taken.
