　　1. How does an air source heat pump work?

　　Air source heat pump is a form of heat pump that can convert low-level thermal energy that cannot be directly used (such as heat contained in air, soil, and water) into usable high-level thermal energy, thereby achieving the purpose of saving some high-level energy (such as coal, gas, oil, electricity, etc.). Air source heat pumps are different from air conditioners. The heating efficiency of air conditioners is not high, and they will not work when the temperature is below -5≧. There is no need to worry about air source heat pumps. The Laurite air source heat pump has a strong low-temperature heating capacity. It uses EVI jet enthalpy increase technology and can provide strong heating at -30≧.

　　On the contrary, air source heat pumps are not only powerful, but also very energy-saving. Mango air source heat pumps use air energy, supplemented by a small amount of electricity, to achieve heating and cooling. One unit of electricity can generate up to four units of heat energy, with an energy efficiency ratio of up to 400%. The main components use variable frequency compressors, variable frequency fans, and variable frequency water pumps, which can perform stepless speed regulation according to changes in the system load, reducing the consumption of useless work and making the unit run more efficiently.Mango air source heat pump has the functions of heating and cooling. It uses air energy and only requires a small amount of electricity to generate three to four times the heat energy. It is more energy-saving and environmentally friendly. Although it is a little more expensive than air conditioning, the service life of air source heat pump is up to 15 years, coupled with lower power consumption. In the long run, using air source heat pump is cheaper and more affordable than air conditioning. Unlike air conditioning, air source heat pump uses a water system, and the air is more moist and gentle during heating, not as dry as air conditioning.

According to a Reuters report on July 16, two Iraq military sources told Reuters that two armed drones attacked an air base in western Iraq where US military and other international troops were stationed on the 16th.

Reported that this is the second attack on U.S. troops stationed in Iraq since early February.

Sources said there were no reports of casualties. An Iraq officer said defense systems shot down a drone near the base.

In April, two drones were shot down near the base, according to a U.S. official.

According to reports, an Iraq army officer said the Iraq army has stepped up patrols around the base to prevent further attacks.

The report said a senior Iraq military delegation is expected to visit Washington in a week to continue negotiations on ending the U.S. -led coalition operations in Iraq.

Washington and Baghdad began negotiations in January to reassess the withdrawal of the U.S. -led coalition from Iraq. The coalition was formed in 2014 to help fight the Islamic State group that then occupied most of Iraq. (Compiled by Guo Jun)
