Abstract
The utility model provides an enforced circulation heat exchange device for a multi-span greenhouse, which comprises a radiator arranged inside a multi-span greenhouse and a hot water pipe connected with the radiator. An underground air duct is arranged inside the multi-span greenhouse. An air inlet and an air outlet of the air duct are respectively positioned at two sides above the ground inside the multi-span greenhouse. The radiator is positioned on the air outlet. A draft fan is arranged inside the air duct. The hot water pipe connected with the radiator is connected with a cool water inlet pipe. The cool water inlet pipe and the hot water pipe are respectively provided with a switching valve. When in the summer, the circulating cool water is provided by the radiator, and the circulating hot water is provided by the radiator in the winter. The utility model makes use of enforced circulation of cool air or hot air formed by the draft fan positioned inside the underground air duct, has temperature-decreasing of the multi-span greenhouse in the summer and the temperature-increasing of the multi-span greenhouse in the winter, provides an appropriate environment for growth and development of the plant and realizes the sustainable and high-efficient production of the whole year.
Description
Technical field:
The utility model relates to a kind of temperature control equipment that is used for attached-greenhouse.
Background technology:
In order to ensure that attached-greenhouse can continue production and highly efficient and productive in the whole year, attached-greenhouse must have the temperature control device of heating in cooling in midsummer, a winter.The attached-greenhouse of northern China (comprise and introduce the greenhouse) is difficult to realize that annual continuing produces owing to there is the shortcoming of the expense height of heating winter, cooling in summer difficulty at present.Both made and not stinted power consumption and survive the winter, problem also is difficult to resolve and determines but lower the temperature midsummer.Existing attached-greenhouse generally adopts the water curtain type falling temperature method, and mainly there are following 2 deficiencies in this method: the one, and the water temperature height, room temperature descends slowly, does not reach the plant growing requirement; The 2nd, high humidity especially reduces night during temperature, and indoor humidity is excessive, very easily causes plant disease, causes heavy losses.
Summary of the invention:
Deficiency in view of above-mentioned prior art existence, the purpose of this utility model provides that a kind of cooling in summer is effective, can assist the attached-greenhouse forced circulation heat-exchange device of heating winter, make it to plant provides an environment that is fit to grow, realize the annual High-efficient Production that continues.
The purpose of this utility model is to realize like this, it comprise be arranged in the attached-greenhouse radiator and the hot-water line that is connected this radiator, it is characterized in that: underground air passage is set in attached-greenhouse, this ventilating duct lay respectively in the attached-greenhouse both sides on the ground into and out of the air port, radiator places the air outlet place, be provided with air-introduced machine in the ventilating duct, connect one and advance cold water pipe on the hot-water line that connects radiator, this advances on cold water pipe and the hot-water line to be respectively equipped with switch valve.During summer, for circulating water, force to form the cold wind circulation in the radiator, realize the cooling in the attached-greenhouse by the air-introduced machine in the underground air passage; During winter, for circulating hot water, force to form hot air circulation in the radiator, make it to improve rapidly the temperature in the attached-greenhouse by the air-introduced machine in the underground air passage.
Characteristics of the present utility model are that the cooling in summer effect is remarkable, through measuring and calculating, start shootings and can reduce room temperature 10 degree in two hours, and it is more obvious especially to reduce the night temp effect, and does not increase indoor humidity, helps preventing plant generation disease; Can assist and heat winter, improves indoor temperature.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cold and hot switching device shifter structural representation of radiator.
Embodiment:
By accompanying drawing as can be known, the utility model mainly comprises and has into and out of the air port 5,1 underground air passage 3 and place the air-introduced machine 4 in this ventilating duct and place the radiator 2 at air outlet 1 place on the ground, this radiator links to each other with hot and cold water pipe 7,6, is respectively equipped with switch valve 9,8 (for realizing that the automatic control switch valve can be a motor-driven valve) on the hot and cold water pipe 7,6.Open switch valve 9, close switch valve 8, can be to radiator 2 pressurization cooling water; Open switch valve 8, close switch valve 9, can be to radiator 2 pressurization heat supply water.Utilize the air-introduced machine semi-finals system in the underground air passage 3 to form cold wind or hot air circulation, make it attached-greenhouse,, realize the annual High-efficient Production that continues for plant provides an environment that is fit to grow cooling in summer or auxiliary in the winter time heating.
