Greenhouses switch to air-source heat pump heating
As we all know, most of the vegetables, flowers must be able to thrive in a warm environment. Cold can be said that these plants "natural enemies," but humans have developed a greenhouse, so that we can see colorful flowers and a variety of vegetables all year round.
Greenhouse is the most critical need to keep warm. In the past, in order to save costs, farmers generally use coal-fired boilers to heat. However, with the continuous implementation of the national "coal to electricity" policy, coal-fired boilers are forbidden to use. Under such circumstances, residents can only look for new green energy-saving heating equipment. The air source heat pump heating with no emissions, low energy consumption, no manual, easy to operate and other advantages in the "coal to electricity" project, much government recommended, was listed as "coal to electricity" project of choice products .
Recently, a wolfberry cultivation base in Sichuan on the use of greenhouse-specific low-temperature air-source heat pump for heating. The difference is that with the traditional heating equipment, air-source heat pump is the use of heat in the air to heat, the higher the ambient temperature, the better energy-saving effect. Even at -25 ℃, low-temperature air-source heat pump can reach more than 2.0 energy efficiency than the direct use of electric heating to save energy by one half.
Air source heat pump is automatic operation around the clock, without the need for dedicated duty automation equipment to ensure that the greenhouse temperature has been in a state of constant temperature suitable for plant growth.
Under the promotion of national energy-saving and emission-reduction policies, air-source heat pumps have become more and more widely used. Air-source heat pumps have not only entered into tens of thousands of households, but also made remarkable achievements in agriculture and aquaculture.
