Need hot water, want to do central air conditioning. I heard that the air can be fine. Is there an air source heat pump that can be done in one step and is very energy-saving?

The heat recovery modular cold and hot water unit is a relatively mature product. In this mode, hot water can be obtained free of charge when air conditioning and refrigeration are carried out in summer, but no hot water is generated when heat control is carried out in autumn and winter, and additional hot water equipment is needed. On the whole, it takes about five months to turn on the air conditioner for refrigeration, saving water 15 tons every day. The main cost saved is electricity, which is about 6,000 yuan a month and about 3W a year in 200 yuan. The initial investment cost of the heat recovery unit is about 10% higher than that of the unit without heat recovery (mainly because the equipment is more expensive and the installation is the same). The initial investment of 4000 square meters air conditioner is about 100W, and the investment of heat recovery type is increased by 654.38 million, and the cost will be recovered in about 3 to 4 years. A hotel with 120 rooms can be equipped with 20 tons of water and 30P host, with an initial investment of about 65,438+10,000.
