Temperature and humidity automatic balance control method and system in water curtain cooling

Abstract

The invention discloses a temperature and humidity automatic balance control method and system in water curtain cooling. According to the current indoor temperature and humidity, a preset standard temperature and a preset standard humidity are compared to control the wet water area including but not limited to a water curtain and thus the current temperature and humidity are stabilized within thestandard temperature and standard humidity range, so that the comfortable environment of the livestock and poultry house is guaranteed, and the dramatically-temperature-changing cooling and/or high-temperature and high-humidity state is avoided. The method comprises the following steps that a standard temperature is set to be P0, a standard humidity is set to be S0, and a maximum difference valueis allowed to be between an allowable temperature and a standard temperature is P1; if the current temperature is larger than P0, a water curtain is started, the wet water area M1 is gradually increased according to the temperature rise, and the indoor temperature and humidity are detected in real time; the wet water area of the water curtain is controlled according to the indoor temperature variable quantity and the indoor humidity variable quantity after the water curtain is started, so that the current humidity is not higher than the standard humidity S0, and the current temperature is nothigher than P0+P1. The system comprises a controller for executing the method, a temperature sensor and a humidity sensor, the temperature sensor and the humidity sensor are connected with the controller, and the controller is provided with a control side connected with a fan, a dehumidifier and a water curtain.

Description

technical field [0001] The invention is applied in the field of breeding, and in particular relates to an automatic temperature and humidity balance control method and system in water curtain cooling. Background technique [0002] The water curtain is to reduce the indoor temperature by expanding the contact area between water and air and accelerating the volatilization of water. However, if the water curtain is opened all at once and completely soaked in a short time, it will cause the indoor temperature to "jump off a cliff". Cooling can reduce 3 degrees Celsius within 30 minutes. At the same time, the continuous opening of the water curtain will lead to an increase in indoor humidity. When the humidity reaches a certain level, the cooling effect of the water curtain will be greatly reduced, but at this time The humidity keeps rising rapidly, and the livestock and poultry houses are in a state of high temperature and high humidity. In this state, the animals raised are pro...

When the humidity reaches a certain level, the cooling effect of the water curtain will be greatly reduced, but at this time The humidity keeps rising rapidly, and the livestock and poultry houses are in a state of high temperature and high humidity. In this state, the animals raised are prone to illness or even death
