Heat supply control system for planting greenhouse

Abstract

The invention discloses a heat supply control system for a planting greenhouse. The heat supply control system comprises a heat exchanger, a circulation pump set, a first heat-preservation water tank, a second heat-preservation water tank, a third heat-preservation water tank, a water supply tube, a water return tube, a cooling water main pipe, a hot water main pipe, 46 air source heat pumps, 2 electromagnetic boilers, a central controller, a temperature acquirer, a temperature controller, a relay set, a valve controller and a touch screen, wherein the temperature acquirer is used for acquiring temperature of water inside the first heat-preservation water tank, the second heat-preservation water tank and the third heat-preservation water tank, and used for transmitting the water temperature information to the central controller; and the central controller is used for transmitting the received water temperature information to the touch screen to display, and used for outputting temperature adjustment instructions to the temperature controller according to control instructions from the touch screen. By adopting the heat supply control system, effective heat supply can be achieved through automatic control.

Description

technical field [0001] The invention relates to the field of greenhouse heating. Background technique [0002] Planting greenhouses in botanical gardens, farms and other places need heating to keep the temperature above 20 degrees Celsius all year round. The heating system generally adopts coal-fired hot water boilers, which not only produce a lot of pollution, but also consume a lot of energy, which makes the cost relatively high. Moreover, in the existing heating system, each water tank is heated independently, and the heat is not uniform and the heating is slow, so the heat storage is relatively slow. At the same time, the uninterrupted nature of manual manipulation increases the cost and is prone to errors. Contents of the invention [0003] The purpose of the present invention is to provide a heat supply control system for planting greenhouses, which can realize effective heat supply through automatic control. [0004] The technical scheme for realizing the above-m...

Problems solved by technology

The heating system generally adopts coal-fired hot water boilers, which not only produce a lot of pollution, but also consume a lot of energy, which makes the cost relatively high

Moreover, in the existing heating system, each water tank is heated separately, the heat is uneven and the heating is slow, so the heat storage is relatively slow

At the same time, the uninterrupted nature of manual control increases the cost and is prone to errors
