Household heat pump heating air-conditioner hot water dehumidifying combined system

Abstract

The invention provides a household heat pump heating air-conditioner hot water dehumidifying combined system. The combined system comprises two heat pump refrigeration systems; the waterways of water- to-water heat exchangers of the two systems are connected in series; the water flow velocity is increased and thermal efficiency is raised; an auxiliary electric water heater is assembled for heating hot water so that allostatic load is added; hot water and hot air are adopted in parallel or in series connection for heating; front-back series connection mode is adopted in the combined water heating radiator so that normal operation of the heat pump can be guaranteed by the circulation return water temperature during heavy load heating in winter; two units are successively used for defrosting during defrosting stage and heating is not interrupted; one refrigerating air-conditioner is used in summer; the refrigeration dehumidifying and heat pump compensation heat circulation are designed; an independent heat pump generates domestic hot water circulation. The system of the invention can be adapted to the variation of loads; muting bedrooms and quick heating for living rooms are realized; the refrigeration air-conditioning amount is reasonable; living hot water is continuously provided; dehumidification and constant temperature are kept for rooms; the utilization rate of devices is high; the technology is reliable; the system has good market prospect.

Description

technical field [0001] The invention relates to the technical field of air conditioning / heat pump heating and hot water systems. Background technique [0002] With the improvement of people's living standards, the areas north of the Yangtze River need heating, air conditioning, hot water and dehumidification. The heating method is usually provided by the municipal hot water pipe network or by the gas hot water boiler to provide 65-75 ℃ hot water to the user, and the user installs a radiator in the room. The radiators of the radiators are connected in parallel to the hot water inlet pipe and the hot water return pipe. The parallel mode ensures that the heat dissipation of each radiator is equal, and the temperature of the radiators of each radiator is basically the same. However, due to various reasons, many residential areas cannot use central heating, and users use too much gas, which is expensive, and heat pump heating is a very energy-saving way. However, the current u...
