Heating and domestic hot water integrated equipment

Abstract

The invention relates to heating and domestic hot water integrated equipment. The heating and domestic hot water integrated equipment comprises an air source heat pump, a heat preservation water tank,a coiled tube type heat exchanger, a temperature controller, heating equipment, an underfloor heating circulating water pump, domestic water equipment, a return water temperature sensor, a return water circulating water pump, a water tank temperature sensor and a cold water inlet. The heating and domestic hot water integrated equipment is reasonable in overall structural design, the air source heat pump heats water in the heat preservation water tank, high-temperature hot water on the upper portion in the heat preservation water tank can be used by the domestic water equipment, middle-temperature hot water on the lower portion in the heat preservation water tank is used by the coiled tube type heat exchanger for heat exchange, heating can be guaranteed, and thus a system meets the needs for domestic hot water and heating at the same time. Cost is reduced, space is saved, and control and use are convenient. In addition, the underfloor heating circulating water pump and the water tank temperature senor guarantee that the domestic hot water is heated preferably in time, the need for the domestic hot water is met, the return water temperature sensor and the return water circulating water pump guarantee that the domestic hot water is instantly heated, and cold water returns into the heat preservation water tank in time.

Description

technical field [0001] The invention relates to heating equipment, in particular to an integrated heating and domestic hot water equipment. Background technique [0002] The air source heat pump is used as the heating host, equipped with a buffer heat preservation water tank, which is used for floor heating or radiator heating; For both heating and sanitary hot water, if the main heat source uses an air source heat pump as the heating host, according to the current product, because heating water and domestic water have different requirements on water quality and temperature, only heating and sanitary heat can be used. One set of equipment is used for each water, resulting in an increase in the initial investment - repeated investment in the main heat source (heat pump) and thermal insulation water tank increases the installation space of the equipment, resulting in limited installation. Therefore, it is urgent to develop a system that can combine heating and domestic water ...
