Abstract
The utility model relates to an automatic water feeding device for a geothermal pump concentrated air conditioner set system. A water feeding pipeline is composed of a one way valve, a water meter and a cut-off valve, and is additionally arranged in a pipeline which is arranged between a geothermy submersible pump and an indoor blower coil pipe. When the pressure of the air conditioner set system of the air conditioner set is lower than the pressure of an underground water system caused by water quantity flowing loss, the water feeding pipeline is used for feeding water to the water circulating system of an air conditioner. The water feeding operation can automatically stop when the pressure of the underground water circulating system and the pressure of the water circulating system of an air conditioner are balanced. The utility model has the advantage of simple structure. Compared with the traditional automatic water feeding system, the cost of the utility model can be ignored. The utility model is particularly suitable for a concentrated air conditioner system of a water-water heat pump machine set.
Description
The technical field of the invention is heat supply and refrigerated air-conditioning system.
In the earth source heat pump central air-conditioning system, for the water circulation system mode of indoor cooling (heat supply) employing fan coil, circulation time will consume a certain amount of water, and in order to reach the purpose of automatic water supplement at any time, present moisturizing has dual mode.A kind of is that extra feed tank is installed, and another is that make-up pump is installed.All there is the device complexity in this dual mode, cost is higher and shortcoming such as inconvenience is installed.
According to the deficiency that traditional water supplementing method exists, it is the air-conditioning system automatic water supplement mode of resource, the i.e. automatic water-replenishing device of earth source heat pump central air conditioning machine set system that the purpose of this utility model provides a kind of being applicable to underground heat.
In Modularly source heat pump refrigerating and heating unit, the recirculated water in the condenser (evaporimeter) of title air conditioner is the open loop groundwater circle system, and claiming indoor cooling (heat supply) to adopt the water circulation system of fan coil is the closed loop water circulation system.Open loop recirculated water moves by immersible pump.System as shown in the figure.The utlity model has immersible pump (1), fan coil (2), check valve (3), water meter (4), stop valve (5), water circulating pump (6), air-conditioning unit (7) etc., in the pipeline of immersible pump (1) and indoor fan coil pipe (water side) (2), install the water pipe that a cover is made up of check valve (3), water meter (4), stop valve (5) additional, the outlet of immersible pump (1) and check valve (3) join, and the water outlet side of stop valve (5) is connected to circulation closed loop water route.During the operation of air conditioner group system, when if fan coil water circulation system pressure is lower than open loop groundwater circle system pressure, the pressured difference of open loop groundwater circle system is opened check valve, water meter, this cover water pipe of stop valve to fan coil water circulation system automatic water supplement.And when two systems (open loop and closed loop) when pressure reaches balance, moisturizing stops automatically.If indoor fan coil pipe water circulation system pressure is during greater than the open loop groundwater circle system, because the effect of check valve is arranged, the water of indoor fan coil pipe water circulation system can not flow backwards to groundwater circle system.Water meter in the water pipe (4) and can add up display system rate of water make-up within a certain period of time except that showing moisturizing situation and rate of water make-up at any time.
Be holding chamber inner blower coil pipe water circulation system operate as normal under specified pressure, a pressure be housed between fan coil (2) and moisturizing pipeline limit protective valve (8).When expanding because of the variation of water temperature produces, the hydraulic pressure of indoor fan coil pipe water circulation system causes that hydraulic pressure increases in the circulatory system; and when increased pressure limits the setting protection pressure of protective valve to pressure; pressure limits protective valve and opens automatically; make water system rush down pressure; reach when setting minimum pressure, pressure limits protective valve and closes automatically.
The utility model is simple in structure, and is easy for installation.Comparing cost with traditional automatic makeup Water System can ignore, but function can reach the purpose of indoor fan coil pipe water circulation system automatic water supplement fully.
The utility model is specially adapted to the central air-conditioning system of water-water heat pump unit, and especially effect is remarkable in the Modularly source heat pump refrigerating and heating unit central air conditioning in places such as hotel, market, dwelling house, amusement uses.
Claims (2)
1. the automatic water-replenishing device of earth source heat pump central air conditioning machine set system, has immersible pump (1), fan coil (2), check valve (3), water meter (4), stop valve (5), water circulating pump (6), air-conditioning unit (7) etc., it is characterized in that in the pipeline between immersible pump (1) and indoor fan coil pipe (water side) (2), install a cover additional by check valve (3), the water pipe that water meter (4) and stop valve (5) are formed, the outlet of immersible pump (1) and check valve (3) join, and the water outlet side of stop valve (5) is connected to the air-conditioning unit circulation waterway between water circulating pump (6) and the indoor fan coil pipe (2).
2. according to the automatic water-replenishing device of the described earth source heat pump central air conditioning of claim 1 machine set system, it is characterized in that between described fan coil (2) and moisturizing pipeline, being equipped with pressure and limit protective valve (8).
