Air source heat pump floor heating system

Abstract

The invention discloses an air source heat pump floor heating system which comprises a circulating water module, an air source heat pump, a heating water tank, a tail end floor heating module, a water pump, an electric heating module, an electromagnetic valve, an expansion tank, a temperature sensor and a controller. An inlet of the circulating water module is connected with the expansion tank, the expansion tank is connected with an inlet of the water pump, an outlet of the water pump is connected with an inlet of the air source heat pump, and an outlet of the air source heat pump is connected with an inlet of the heating water tank. According to the air source heat pump floor heating system, the frequency of the adopted water pump can be automatically adjusted according to the probability of indoor opening, the main engine starting and stopping frequency caused in the circumstance of the large heating capacity of an indoor low load device can be easily reduced, the speed of decreasing of the overall water temperature can be reduced in a defrosting mode, the floor can be heated more rapidly in the primary heating period of a floor heating system, waiting time of users is shortened, and the pressure of the system cannot be reduced in the circumstance that outside water pressure is insufficient.

Description

technical field [0001] The invention relates to a floor heating system, in particular to an air source heat pump floor heating system. Background technique [0002] Low-temperature floor radiant heating is a system that uses the ground inside the building for heating. It uses low-temperature hot water as the heat medium, heats the floor through plastic pipes buried in the floor, and uses the entire ground as a heat dissipation surface to radiate evenly into the room. Heat, an energy-efficient heating system that regulates the microclimate of a room. [0003] Low-temperature floor radiant heating gives people the comfort of warming the feet and cooling the head, which conforms to the physiological adjustment characteristics of the human body, conforms to the ideal feeling of the human body, and can promote the blood circulation of the human body. Gradually, it has been widely recognized in the market. Due to its energy saving, safety and environmental protection, air source ...
