Description

Soil-source heat pump system for heating and humidifying phalaenopsis planting greenhouse
Technical field
The present invention relates to technical field of air conditioner refrigeration, particularly a kind of iris cultivation greenhouse heating humidification soil source heat pump System.
Background technology
Currently, energy scarcity has become the key issue of serious restriction China socio-economic development, and energy-conservation is used as country One important component part of energy strategy.In cultivation of some rare flowers such as iris, have very high to humiture Requirement, general winter demand indoor temperature be not less than 15 DEG C, Summer Indoor temperature be not more than 28 DEG C, annual indoor humidity is not little In 80%, it is to meet to require, on modern market to adopt coal-burning type boiler and hot-air blower to heat, wet curtain humidification, with the system energy more Consumption is big, and land occupation resource is more, and summer cooling is difficult.From energy consumption is reduced, CO is reduced2And SO2From the point of view of pollutant, application is now On market, the source pump of electrical energy drive replaces coal-burning type boiler.From from the perspective of the Cooling and Heat Source of system, heat pump can be divided into again Air source heat pump, water resource heat pump and soil source heat pump etc..In greenhouse heating application, coal-burning type boiler, water resource heat pump and air Source heat pump all Shortcomings.
