Description

There is the binary channels hot water assisted heating device of commutation function
Technical field
The invention discloses a kind of hot-water heating system, particularly a kind of binary channels hot water assisted heating device with commutation function.
Background technology
In the hot-water heating system of current use, some hot water used in system water supply point and hot water are distant between using a little, hot water needs to flow through quite long pipe-line system could arrive hot water use point, as hot-water heating systems such as central heating net, gas heater, solar water heater or heat pumps, from kitchen to toilet, the hot water of solar energy balcony wall hanging system water tank is from balcony to toilet or to kitchen, system pipeline is longer, and user generally needs to bleed off the hot water that just can use needs in pipeline after cold water.This hot-water heating system can cause larger thermal resource and water resource waste and bad Consumer's Experience.
In addition, in the hot-water heating system water tank being thermal source with regenerative resources such as solar energy, earth source heat pump or air source heat pumps, the general positive displacement water box that adopts stores the hot water produced by regenerative resource; When the water temperature in water tank does not reach the instructions for use of user, such as the electric heater of the assisted heating device in general water tank heats the warm water in water tank, to reach the temperature required by user.
In current this hot-water heating system, supplementary energy such as electric heater needs to heat the water in whole water tank, to reach the leaving water temperature of user's setting, and user often only uses part or small part to be heated to the hot water of higher temperature, causes certain energy waste; On the other hand, the low temperature exhaust heat stored in hot-water heating system water tank is (lower than human body preference temperature, as the low-temperature water heating below 37 DEG C, water temperature now by regenerative resource heat temperature raisings such as solar energy 20 ~ 30 DEG C) but can not be utilized effectively, causing a large amount of energy wastes, is cause the regenerative resource such as solar water heater or Teat pump boiler hot-water heating system heat energy to imitate lower main cause.
Summary of the invention
For overcoming the deficiency of the regenerative resource hot-water heating systems such as existing hot-water heating system and solar energy, improve the utilization rate that regenerative resource produces hot water, reduce supplementary energy consumption, the present invention proposes to have the binary channels hot water assisted heating device of commutation function, comprising reversal valve and the supplementary energy heating water tank etc. that can heat the low-temperature water heating of cold water in pipeline and external heat source.
Main feature of the present invention is: the commutation node between the supplementary energy heating water tank heated using self-operated type constant-temperature three-way diverter valve (ZL201220274480.7) or the reversal valve such as electric T-shaped valve, three-way solenoid valve as pipeline cold water or external heat source low-temperature water heating and carrying out, realizes the switching of current of the present invention between hot-water heating system hot water channel;
When entering assisted heating device, during the design temperature of the current water temperature flowing through reversal valve higher than reversal valve, self-operated type constant-temperature three-way diverter valve (ZL201220274480.7) or the reversal valve such as electric T-shaped valve, three-way solenoid valve high-temperature water outlet mouth are opened, low temperature delivery port is closed, high-temperature water flows through the first hot water channel to heater hot water outlet, for with water spot;
When the design temperature of the current water temperature flowing through reversal valve lower than reversal valve, reversal valve high-temperature water outlet mouth is closed, low temperature delivery port is opened, water at low temperature is switched to the water inlet of auxiliary heating water tank, in water tank, hot water is through the second hot water channel to heater hot water outlet, for water spot, realizes instant-heating, start the heater of auxiliary heating water tank simultaneously, the water at low temperature flowing into water tank is heated.
The technical solution adopted in the present invention is: system is primarily of auxiliary heating water tank, and the composition such as the reversal valve such as self-operated type constant-temperature three-way diverter valve or three-way solenoid valve system, reversal valve water inlet is connected with external heat source hot water feeding pipe road, two delivery ports of reversal valve are respectively at auxiliary heating water tank water inlet, hot water outlet connects, and with forming two hot water channels between water spot, the water outlet water (flow) direction of reversal valve is controlled according to the current water temperature height entering reversal valve, different water temperature current are made to enter different hot water channels, reach instant-heating, preferential use external heat source hot water, and make full use of the object of external heat source low temperature exhaust heat.
The invention has the beneficial effects as follows:
1, effectively solve hot water with water spot " instant-heating ", avoid external heat source and the waste with cold water in pipeline between water spot.
2, the hot water that external heat source (concentrated hot watersystem, gas heater, solar water heating system, heat pump hot-water system etc.) provides preferentially is used.
3, by utilizing hot-water heating system middle-low temperature heat, the actual object reaching expansion external heat source water tank capacity, increase the effective hot water supply of external heat source water tank and saving supplementary energy.
4, the life-span avoiding the water sources such as solar energy to bring to assisted heating device because of HTHP and the reduction of reliability.
