Description

Swimming pool dehumidifying heat pump type air conditioning system

Technical field

The utility model relates to the special-purpose dehumidifying of swimming pool heat pump, particularly relates to the special-purpose dehumidifying of the swimming pool source pump that has dehumidifying, heat pump functional simultaneously.

Background technology

Along with people's is to the attention of health with to the pursuit of high-quality life, and swimming pool becomes the place of people's favor gradually, and comfortable, healthy, energy-conservation, friendly type swimming pool arises at the historic moment.

The air conditioning parameter of indoor swimming pool is generally got as follows:

Require air themperature higher 1～2 ℃ simultaneously than swimming pool water temperature.

Can be found out that by above-mentioned data if the air of indoor swimming pool keeps constant temperature and humidity, Chi Shui to keep constant temperature, then Chi Shui and air exist partial pressure of water vapor poor, Chi Shui is to the Room, pond air evaporation water vapour, and therefore indoor swimming pool needs to dehumidify the whole year.

The humidity load in the Room, swimming pool pond in summer is made up of pond evaporation of water (evaporation in the wet district of bag pool side), new wind, personnel's evaporation;

The humidity load in the Room, swimming pool pond in winter is made up of pond evaporation of water (comprising the evaporation in the wet district of pool side), personnel's evaporation; The new wind in winter is dehumidification;

The pool water surface of maximum wet source for opening wide in the swimming pool Room, its moisture dispersed amount is (a pond evaporation of water amount):

W1＝β×F×（α＋0.0174×V）×（P2-P1）×（PB/P）

The total surface area of F---water evaporates, m ²

α---the diffusion coefficient under the different water temperatures;

The speed air flow of V---evaporating surface, m/s;

P1---corresponding to saturated steam partial pressure under the water surface temperature, mmHg;

The steam partial pressure of P2---air, mmHg;

PB---standard atmospheric pressure, mmHg;

Real atmosphere is pressed in P---the engineering, mmHg;

β---the correction factor of central air-conditioning is arranged in the room.

Because annual pond water temperature, the air themperature in the Room, pond, relative humidity are to keep constant, therefore, the evaporation capacity of the pond water surface is constant, and what differ is the humidity load of new wind; The new wind of the Room, pond personnel needs, the needs of the chloride air of displacement because the Room, swimming pool pond is for keeping again, need that is to say that humidity load in summer (amount of humidification), the humidity load in winter (dehumidification amount) of new wind are bigger than the bigger resh air requirement of general conventional comfort air conditioning system.

This just causes total humidity load in summer in the Room, pond, total humidity load in winter to differ bigger, total humidity load in general winter be summer total humidity load 60～90%;

The type selecting of the general Room, pond dehumidifier is the humidity load according to summer, and this just causes, and the unit dehumidifying effect is excessive in the winter time, and unit part ability is idle, the initial cost waste; And the thermic load in winter is bigger, and the Room, pond needs more heating capacity.

Therefore the Room, swimming pool pond adopts special-purpose dehumidifier to add the scheme of auxiliary thermal source in the winter time, and with heat, the thermic load that satisfies the Room, pond, it is energy-conservation to compare the tradition ventilation dehumidifying, but energy consumption is still bigger.

The utility model content

The purpose of the utility model is to overcome the deficiency of the special-purpose dehumidifier of general swimming pool, improves the unit utilization ratio, reduces the heating load of auxiliary thermal source in winter, to save initial cost, improves efficiency of energy utilization simultaneously.

The technical scheme that the utility model adopts is:

A kind of swimming pool dehumidifying heat pump type air conditioning system; Comprise first refrigeration cycle; Also comprise second refrigeration cycle, be provided with four-way change-over valve in said second refrigeration cycle, change the Chinese refrigerant flow direction of said refrigeration cycle through said four-way change-over valve; Make evaporimeter and condenser change, thus the change that realization is freezed or heated.

Said second refrigeration cycle comprises compressor, expansion valve, evaporimeter, pond water condenser, four-way change-over valve, air-conditioning condenser, air-conditioning draught fan; Wherein, The port of export of compressor is connected with the entrance point of pond water condenser; The port of export of four-way change-over valve difference connection pool water condenser, the entrance point of air-conditioning condenser, the entrance point of compressor, the port of export of evaporimeter, the port of export of air-conditioning condenser connects the entrance point of expansion valve, and the port of export of expansion valve connects the entrance point of evaporimeter.

Beneficial effect:

The humidity load that the utility model takes into full account the Room, swimming pool pond summer, winter is different, reduces assistant heating amount in winter, reduces initial cost, and the unit utilization rate is provided, and adopts heat pump to heat simultaneously, saves the energy.
