Abstract

The utility model relates to a device for utilizing waste heat of central air conditioners to prepare hot water and a use method. The device is provided with an evaporator 1 and a condenser 4 which are mutually communicated by a pipe. A compressor 2 and a throttle expansion valve 3 are connected with the evaporator 1 and the condenser 4 in between by pipes. When in use, a water inlet pipeline and a water outlet pipeline of the evaporator 1 are connected with a water pipe of a cooling water or chilled water system of an externally set central air conditioner by pipes. A water inlet pipeline and a water outlet pipeline of the condenser 4 are connected with a water inlet pipeline and a water outlet pipeline of an externally set hot water tank by pipes. When the central air conditioner runs, the device is started, the obsolete hot water enters the evaporator to provide a heat source, the condenser transfers the heat to the water of the water tank to heat, the energy consumption is 25%-30% of the energy consumption of the traditional device, and the water temperature achieves more than 50 DEG C. The utility model can satisfy the heat supply requirements for urban residents of southern areas without groundwater in spring, summer and autumn three seasons.

Description

A kind of device that utilizes central air-conditioning used heat to produce hot water

Technical field

The utility model relates to a kind of heating system, relates in particular to a kind of cooling or the low-grade exhaust heat of refrigerant system device of converting high-grade heat energy to air-conditioner.

Background technology

China resident's health hot water except that a part is power plant's centralizedly supply, is almost supplied with for the fuel boiler that disperses entirely at present.These heating plants not only discharge large quantity of exhaust gas, refuse, bring serious environmental to pollute, and because of the low severe energy waste that causes of its thermal efficiency.Along with the intensification of global energy crisis and watchful to environmental issue, people recognize gradually and utilize heat pump to come hot-water supply.But many places there is no the water source, so water resource heat pump is not just arranged use.Have to produce health hot water with fuel oil or gas fired-boiler.And meanwhile, central air-conditioning looses the heat energy in the floor among the air in the external world in vain by cooling water, for this increases hot somewhat again in city of dysphoria with smothery sensation.

The utility model content

The technical problems to be solved in the utility model is, defective at the prior art existence, a kind of device that utilizes central air-conditioning used heat to produce hot water is provided, and the waste heat recovery of utilizing this device air-conditioner can be discharged is with environmental protection, mode is produced health hot water cheaply.

Technical solution of the present utility model is, the described device that utilizes central air-conditioning used heat to produce hot water, as shown in Figure 1, have mutual pipe logical evaporimeter 1 and condenser 4, pipe is connected to compressor 2 and throttle expansion valve 3 between described evaporimeter 1 and the condenser 4, wherein the delivery outlet pipe of evaporimeter 1 connects the input port of compressor 2, the input port pipe of evaporimeter 1 connects the delivery outlet of throttle expansion valve 3, the input port pipe of described condenser 4 connects the delivery outlet of compressor 2, and the delivery outlet pipe of condenser 4 connects the input port of throttle expansion valve 3.

When the device that utilizes central air-conditioning used heat to produce hot water of use said structure is produced hot water, the water-in and water-out pipeline of the evaporimeter 1 of said apparatus and the cooling water of peripheral hardware air-conditioner or the water pipe pipe of chilled-water system can be connect, the water-in and water-out pipeline of the condenser 4 of said apparatus is connect with the going out of peripheral hardware boiler, water inlet pipe deferent successively.

Operation principle of the present utility model is, when the peripheral hardware air-conditioner moves, start this device, start boiler circulation force (forcing) pump, open the evaporimeter two ends valve of this device, enter evaporimeter from the discarded hot water of the work system of air-conditioner and provide thermal source to it, this device is passed to water to be heated in the water tank to the heat that absorbs by condenser again, when water temperature in the water tank reaches design temperature for example during 50 ℃ of left and right sides, this device quits work.

The beneficial effects of the utility model are:

1, save cost: spring, summer, Qiu Sanji can directly utilize the cooling of central air-conditioning or chilled-water system to produce health hot water.Use energy consumption of the present utility model only to be equivalent to the 25%-30% of former heating equipment energy consumption, greatly saved operating cost.

2, applied widely: as to be applicable to the user that all have central air-conditioning and need health hot water.

3, market prospects are good: present technique supply water temperature height, and the Energy Efficiency Ratio height, operating cost is low, and is pollution-free, and therefore vast market prospect is arranged.

Description of drawings:

Fig. 1 is that the utility model utilizes central air-conditioning used heat to produce the combining structure and the operation principle schematic diagram of the device of hot water, is denoted as among the figure:

1-evaporimeter,

2-compressor,

3-throttle expansion valve,

4-condenser.

The specific embodiment:

Referring to Fig. 1, the central air-conditioning used heat that utilizes of present embodiment is produced the device of hot water, and its evaporimeter 1 adopts commercially available common air-conditioning type evaporimeter; Condenser 4 adopts commercially available common air-conditioning condenser.Pipe is logical mutually between this evaporimeter 1 and the condenser 4.The compressor 2 employings power produced in USA that pipe is connected between this two utensil is the CL-50R type compressor of 50Kw.The throttle expansion valve 3 that pipe is connected between this two utensil also adopts commercially available common throttle expansion valve.The delivery outlet pipe of above-mentioned evaporimeter 1 connects the input port of compressor 2, and the input port pipe of evaporimeter 1 connects the delivery outlet of throttle expansion valve 3, and the input port pipe of above-mentioned condenser 4 connects the delivery outlet of compressor 2, and the delivery outlet pipe of condenser 4 connects the input port of throttle expansion valve 3.

When using the device of said structure to produce hot water, the water-in and water-out pipeline of the evaporimeter 1 of said apparatus and the cooling water of peripheral hardware central air-conditioning or the water pipe pipe of chilled-water system are connect, and join the valve that is complementary with caliber.The water-in and water-out pipeline of the condenser 4 of said apparatus is connect with the going out of peripheral hardware boiler, water inlet pipe deferent successively.Also be equipped with the valve, stop valve and the water pump that are complementary.

The device that the used heat that utilizes central air-conditioning of the present utility model that constitutes is thus produced health hot water is to draw by-pass line and valve inserts in the pipe network of original heating system and refrigeration system, its evaporimeter water inlet pipe inserts in the cooling system water outlet or chilled water inlet channel of air-conditioner, on the water inlet of outlet pipe access cooling system or the outlet conduit of chilled water.And its condenser water inlet pipe inserts on the boiler outlet conduit, and outlet inserts on the boiler inlet channel.In original central air conditioner system and health hot water heating, introduce this device, utilize central air-conditioning used heat to produce health hot water.Be proved to be respond well through manufacturing experimently to try out, when normally moving, supply water temperature reaches more than 50 ℃.Economic performance can satisfy the heat supply that southern area does not have underground water source city spring, summer, Qiu Sanji between 200～800%.
